Full textOs óxidos mistos CeO2-ZrO2 são utilizados como suporte de catalisadores automotivos devido a sua capacidade de estocar e liberar oxigênio em condições pobres ou ricas de combustível, respectivamente, a fim de auxiliar nas reações redox que minimizam a emissão de poluentes oriunda da queima incompleta do combustível. Neste trabalho, os óxidos mistos CeO2-ZrO2 foram preparados pelo método de coprecipitação, utilizando-se como sais precursores o ZrO(NO3)2 e o (NH4)2Ce(NO3)6 ou Ce(NO3)3 com a finalidade de se observar a influência do sal precursor de cério no sistema CeO2-ZrO2. Além disso, investigou-se o efeito de algumas condições de preparação como o envelhecimento do precipitado, o controle de pH durante a síntese, a secagem e o envelhecimento térmico nos óxidos mistos obtidos. Os resultados mostram que a variável mais significante na preparação dos óxidos mistos CeO2-ZrO2 por coprecipitação é o sal precursor de cério. Em todas as amostras preparadas a partir do precursor de cério IV houve a formação de solução sólida, enquanto que no caso das amostras preparadas a partir do precursor de cério III observou-se a formação de duas fases segregadas, c-CeO2 e t-ZrO2. Além disso, concluiu-se que a redução do material obtido não ocorre somente na superfície, mas também na parte mássica e que os materiais formados por solução sólida são os que apresentam melhor capacidade de armazenamento de oxigênio o que é muito importante para o uso em catalisadores automotivos. O envelhecimento térmico do catalisador mostrou que há uma sinterização devido à alta temperatura e que também há uma segregação da solução sólida quando esta foi submetida às condições de envelhecimento utilizadas.
The CeO2-ZrO2 mixed oxides are used as automotive catalyst support due to their capacity to storage and to release oxygen in lean and rich conditions, respectively, in order to assist redox reactions that minimize the emission of pollutants caused by fuel incomplete combustion. In this present work, the CeO2- ZrO2 mixed oxides had been prepared by the coprecipitation method using as precursor salts the ZrO(NO3)2 and the (NH4)2Ce(NO3)6 or the Ce(NO3)3 with the purpose of observing the influence of the cerium precursor salt in the CeO2-ZrO2 system. Moreover, the effect of some preparation conditions like drying, thermal aging, pH control and aging along precipitation was investigated. The results show that the most significant variable in the coprecipitation preparation of the CeO2-ZrO2 mixed oxides is the cerium salt precursor. There were formation of solid solutions in all samples prepared from the cerium IV precursor, while in the case of the samples prepared from the cerium III precursor, it was observed formation of two segregated phases, c-CeO2 and ZrO2. In addition, one concluded that the reduction of the obtained material does not only occur in the surface, but also in the bulk. The solid solution materials are the ones that present the best oxygen storage capacity what is very important for the use in the automotives catalysts. The thermal aging of the catalyst showed that there are a sintering due to the high temperature and a segregation of the solid solution when the material was submitted to the used aging conditions.

Full textThe objective of this work was to investigate the influence of the critical micelle concentration of the CTAB surfactant on the synthesis of the compound Zn0.25Mn0.75Fe2O4 (Frankilinite) by the coprecipitation method and then processing fractions of the synthesized material by hydrothermal treatment. The magnetic characterization was performed by AC susceptometry, being possible to determine the magnetic susceptibility and the dissipated energy. The FTIR analysis identified two phases, Frankilinite and Akaganéite. The structure and morphology of the nanoferrites were analyzed by X-ray diffraction and it was shown that the samples synthesized by coprecipitation only presented the tendency to increasing of crystallite sizes of the akaganéita phase and decreasing of crystallite sizes of the Frankilinite phase as a function of CTAB concentration. The samples submitted to subsequent hydrothermal treatment presented a tendency to decreasing the crystallite sizes of both phases and increasing in Frankilinite phase fraction, compared to the samples synthesized only by coprecipitation, suggesting that the hydrothermal treatment was effective in obtaining nanostructured materials of smaller particles.

Ceramic powders based on oxides of perovskite-type structure is of fundamental interest nowadays, since they have important ionic-electronic conductivity in the use of materials with technological applications such as gas sensors, oxygen permeation membranes, catalysts and electrolytes for solid oxide fuel cells (SOFC). The main objective of the project is to develop nanostructured ceramic compounds quaternary-based oxide Barium (Br), Strontium (Sr), Cobalt (Co) and Iron (Fe). In this project were synthesized compounds BaxSr(1-x)Co0, 8Fe0,2O3- (x = 0.2, 0.5 and 0.8) through the oxalate co-precipitation method. The synthesized powders were characterized by thermogravimetric analysis and differential thermal analysis (TGADTA), X-ray diffraction (XRD) with the Rietveld refinement using the software MAUD and scanning electron microscopy (SEM). The results showed that the synthesis technique used was suitable for production of nanostructured ceramic solid solutions. The powders obtained had a crystalline phase with perovskite-type structure. The TGA-DTA results showed that the homogeneous phase of interest was obtained temperature above 1034?C. It was also observed that the heating rate of the calcination process did not affect the elimination of impurities present in the ceramic powder. The variation in the addition of barium dopant promoted changes in the average crystallite size in the nanometer range, the composition being BSCF(5582) obtained the lowest value (179.0nm). The results obtained by oxalate co-precipitation method were compared with those synthesis methods in solid state and EDTA-citrate method

Full textIn the context of modern search and investigation of alternative energy sources, electrochemical energy storage and convertion systems occupy a significant niche. Open for research issue, related to electrochemical energy sources, is the development and search of efficient, environmentally friendly and cost-effective catalysts for fuel cells. A promising direction in this area is the study of mixed oxide catalysts, namely catalysts with a spinel structure. The compound that attracts considerable attention in this area is the Ni-, Co-spinel of the NiCo2O4 composition and its various composite materials with the developed surface carrier. The object of the study is Ni-, Co-spinels and their composites with multiwalled carbon nanotubes and activated carbon. The subject of the study is the synthesis, physical and chemical properties of Ni-, Co-spinels and their composites with multiwalled carbon nanotubes and activated carbon. The research method is experimental. During the work, the structural characteristics and surface morphology of the samples were investigated using methods of low-temperature N2 adsorption-desorption, scanning electron microscopy and X-ray diffration. The catalytic activity of the synthesized samples was investigated in the course of a model liquid-phase heterogeneous-catalytic reaction of sodium borohydride hydrolysis and decomposition of hydrogen peroxide. The ion exchange characteristics of the synthesized samples surface were investigated during pH-tertiometric titration. A simple and technological method of co-precipitation was proposed as a synthesis method. Pure nickel cobaltite and its composites with active carbon and carbon nanotubes were synthesized. As the obtained data showed, the synthesized samples possess all the properties of an effective catalyst that can be used in electrochemical energy sources. The synthesized composite materials can be used in a variety of electrochemical storage and energy conversion devices, including direct borohydride fuel cells.

The objective of this study is to discover a new co-precipitation method for the synthesis of delafossite CuFeO2 powders at 90oC in ambient environment. Tetramethylammonium hydroxide, the capping agent, and ethylenediamine, the chelating agent, are used to control the precipitation rate of copper and iron ions during the formation of the binary metal oxide. All products are measured by using XRD, XPS, and VSM. The XRD analyses show that the products are mainly composed of delafossite CuFeO2 with trace of tenorite (CuO) and maghemite (Fe2O3). XPS spectra also confirm the bivalent states of copper ions in the samples. The magnetization for particles synthesized at low temperature is very weak. Finally, methylene blue was used as the target pollutants in the photocatalytic degradation reaction, 88.3 % of methylene blue was removed in 150 minutes. It was found that CuFeO2 powders could effectively degrade methylene blue. Photocatalytic degradation of methylene blue has been investigated in CuFeO2 aqueous suspensions. 88.3% of methylene blue is decomposed within 150 min using CuFeO2 powders as the catalyst.

CexZr1-xO2 (1〉x〉0, CZ) has unique oxygen storage capacity (OSC) which can be applied in three way catalysts to promote emission conversion efficiency. But, CZ appeared phase separation after high temperature treatment which deteriorated the OSC. The redox properties of CZ are strongly dependent on the crystal phase, texture and homogeneity. However, the explanation and mechanism for the improved redox properties were not fully resolved yet, and the conclusions still existed controversies. The aims of this study were to observe the phase separation behavior and investigate the phase separation mechanism of Ce0.6Zr0.4O2 (C60Z) prepared by chemical coprecipitation method. The redox properties of C60Z were observed under alternate reduction/oxidation atmosphere. Furthermore, the effects for the addition of aliovalent cations to the influence of C60Z phase separation were also investigated. The phase separation of C60Z appeared during heating stage which might belong to thermal activated process. We observed the phase separation phenomenon of C60Z calcined at 1000 °C for various durations. The original c'-C60Z gradually separated into c+t phases and the compositions of the two separated phases were gradually changed with the duration time. The A. N. ratios of C60Z increased rapidly in the beginning of phase separation, indicating that C60Z tended to aggregate together. And it also exhibited that the texture behavior of C60Z was grain boundary dominated during phase separation. The phase separation mechanism of C60Z was interface controlled and the activation energy for phase separation was 398(±20) kJ/mol from the kinetic results. We found that Zr enriched at the interface between particles after the appearance of C60Z phase separation from the TEM observation,, which was very similar to the initial stage of sintering and exhibited that Zr+4 played an important role in C60Z phase separation. The diffusion rate of Zr+4 is faster than that of Ce+4 due to the smaller ionic radius of Zr+4 than that of Ce+4. The driving force for phase separation was from the surface energy difference between crystallite surface and interface. Hence, Zr+4 diffused to the interface between particles to lower the surface energy of the system, which resulted in the composition gradually change and led to phase separation. The C60Z powders tended to aggregate in advance to create the surface energy difference between crystallite surface and interface, which induced Zr+4 diffused to the interface between crystallites and appeared C60Z phase separation. We observed other different Ce/Zr ratios of CZ (C77Z and C26Z) samples calcined at 1000 °C for various durations. It took longer duration time for the appearance of C77Z phase separation than that for the C60Z and C26Z. There are more Ce contents in C77Z than that in C60Z and C26Z, which resulted in Zr movement difficult and retarded phase separation. The single cubic C60Z powders transformed into cation-ordering pyrochlore structure after calcinations at 1200°C for 2h under a reducing atmosphere, and no phase separation appeared. The two separated phases (Ce-rich and Zr-rich phases) obtained after calcinations at 1100°C for 2 h transformed into a pyrochlore structure after heat treatment at 1490°C under a reducing atmosphere , and then this structure transformed into separated phases after further calcination at 1200°C for 2h in air, suggesting that the order-disorder phase transformation under reduction/re-oxidation treatment might be attributed to Zr diffusion. The reduction peak and the reduction fraction were shifted to higher temperatures and the OSC was also deteriorated after the appearance of phase separation for C60Z. The inhomogeneity originating from the phase separation may inhibit the oxygen release in the CZ system. The influences of Al+3 or Ba+2 additions to C60Z phase separation were also investigated. The ACZ-C powders synthesized by chemical coprecipitation method could prevent crystallite aggregation and growth, which inhibited C60Z phase separation. The results of ACZ-C were consistent with the interface controlled mechanism of C60Z phase separation. Besides, The OSC properties of ACZ-C were also improved. The addition of an appropriate amount of Ba+2 ions into C60Z by impregnation method was effective in retarding phase separation, and increasing the specific surface area of C60Z. Ba+2 would react with Zr of C60Z to form BaZrO3 which provided active oxygen species between the interfaces of C60Z and BaZrO3, and also promoted OSC.

Layered double hydroxide (LDH) is a layered structure material consisting of divalent and trivalent metal hydroxides, wherein the anion compounds and water are replaceable. As a result, LDH can function like an anion exchanger. The LDH composite integrated with magnetic component could be recovered by magnet and used in establishing a separation process without centrifugation and filtration. A simple route for preparing a magnetic LDH with high adsorption capacity is still a challenge work. Accordingly, this article proposed a two-stage synthetic method for preparing a high adsorption capacity magnetic LDH material. First, the magnetic silica cores (Fe3O4@SiO2) were covered with aluminum isopropoxide to form the aluminum hydroxide (AlOOH) layer which was severed as the seed layer for LDH growth. Then, the LDH shell was fabricated by co-precipitation reaction of zinc nitrate, magnesium nitrate, and urea. The resultant core-shell magnetic LDH composite (Fe3O4@SiO2@ZnMgAl-LDH) was characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), and the surface area and pore size analyzer (BET). TEM images showed the radius of the magnetic core (Fe3O4@SiO2) was 60 nm, the LDH sheet was 50-150 nm long and 1-2 nm wide. The as-prepared magnetic LDH was mesoporous with a pore diameter of 6.5 nm and a specific surface area of 360 m2/g material. Methyl orange (isoelectric point (pI) = 3.1) was employed as the adsorbate for investigating the adsorption properties of the Fe3O4@SiO2@ZnMgAl-LDH. The adsorption capacity decreases as the increase in temperature. In addition, the highest adsorption capacity was in the range of pH 5-6 and reached to the level of 2800 mg/g adsorbent at 25°C, implying that the adsorption behavior was governed by the electrostatic interaction. The adsorption behavior of Fe3O4@SiO2@ZnMgAl-LDH could be well fitted with Dubinin-Radushkevich model, indicating that the adsorption ability among various adsorption sites were different. The time course adsorption study demonstrated that the adsorption of methyl orange by Fe3O4@SiO2@ZnMgAl-LDH approached pseudo-second kinetics; therefore, chemical adsorption may dominate the whole adsorption process. Additionally, the whole adsorption process may involve three stages: exterior diffusion, interior diffusion and equilibrium stage. The seed layer-coprecipitation method proposed in this article can fabricate high adsorption capacity magnetic LDH composite and develop novel the magnetic adsorbents with high adsorption ability.
