Texto completoVery few systems allow the study of the relationship between structural changes and physical properties in such a clear way as rare earth nickelate ReNi03 perovskites (Re (rare earth) = Pr, Nd, Sm and Gd). Synthesized for the first time by Demazeau et al [1] in 1971 and completely forgotten for almost twenty years, these compounds have regained interest since the discovery of high-temperature superconductivity and giant magnetoresistive effects in other perovskite-related systems. Due to its Metal-Insulator Transition (MIT) and thermochromic properties, the rare earth nickelate perovskite ReNi03 has received a great deal of attention for the past ten years in their thin films form [12]. Such unusual electronic and optical features are all the more interesting since the metal-insulator transition temperature (TMn) can be tuned by changing the Re cation: LaNi03 is metallic. No minimum of the metallic conductivity of Sm0 . ssNd 0.45Ni03, as observed by Gire et al [12] (entropic effect), was reported by Ambrosini and Hamet [11]. It has been suggested by Obradors et al. [13] that changing the rare earth cation in the ReNi03 system, acts as internal chemical pressure (increasing internal pressure by substituting the rare earth cation with another one of larger ionic radius) which can lead, as for the isostatic pressure experiment, to a tunability of the metal-insulator transition temperature [14, 15]. Obradors et al [13] reported on a decrease of T MIT upon increasing isostatic pressure but with remaining metallic properties of PrNi03 and NdNi03 (same magnitude and thermal dependence of the electrical resistivity)

The mixed metal oxides constitute an important class of catalytic materials widely investigated in different fields of applications. Studies of rare earth nickelates have been carried by several researchers in order to investigate the structural stability afforded by oxide formed and the existence of catalytic properties at room temperature. So, this study aims synthesize the nanosized catalyst of nickelate of lanthanum doped with strontium (La(1-x)SrxNiO4-d; x = 0,2 and 0,3), through the Pechini method and your characterization for subsequent application in the desulfurization of thiophene reaction. The precursor solutions were calcined at 300?C/2h for pyrolysis of polyester and later calcinations occurred at temperatures of 500 - 1000?C. The resulting powders were characterized by thermogravimetric analysis (TG / DTG), surface area for adsorption of N2 by BET method, X-ray diffraction (XRD), scanning electron microscopy (HR_SEM) and spectrometry dispersive energy (EDS). The results of XRD had show that the perovskites obtained consist of two phases (LSN and NiO) and from 700?C have crystalline structure. The results of SEM evidenced the obtainment of nanometric powders. The results of BET show that the powders have surface area within the range used in catalysis (5-50m2/g). The characterization of active sites was performed by reaction of desulfurization of thiophene at room temperature and 200?C, the relation F/W equal to 0,7 mol h-1mcat -1. The products of the reaction were separated by gas chromatography and identified by the selective detection PFPD sulfur. All samples had presented conversion above 95%
Os ?xidos met?licos mistos constituem uma importante classe de materiais catal?ticos mundialmente investigados em diferentes campos de aplica??es. Estudos envolvendo niquelatos de terras raras v?m sendo realizados por v?rios pesquisadores no intuito de investigar a estabilidade proporcionada pelo ?xido estrutural formado e a exist?ncia de propriedades catal?ticas, ? temperatura ambiente. Neste contexto, este trabalho tem como objetivo a s?ntese do catalisador nanom?trico de niquelato de lant?nio dopado com estr?ncio (La(1-x)SrxNiO4-d; x = 0,2 e 0,3), atrav?s do m?todo Pechini e caracteriza??o para posterior aplica??o em rea??o de dessulfuriza??o de tiofeno. As solu??es precursoras foram calcinadas a 300?C/2h, para pir?lise do poli?ster e posteriores calcina??es foram realizadas nas temperaturas entre 500 - 1000?C. Os p?s resultantes foram caracterizados por an?lise termogravim?trica (TG/DTG), ?rea superficial por adsor??o de N2 pelo m?todo BET, difra??o de raios x (DRX), microscopia eletr?nica de varredura de alta resolu??o (HR_MEV) e espectroscopia por energia dispersiva (EDS). Com os dados de an?lise t?rmica, foi poss?vel definir as temperaturas e calores envolvidos no processo de decomposi??o dos ?xidos finais. Os resultados de DRX mostraram que as perovisquitas obtidas s?o constitu?das de duas fases (LSN e NiO) e a partir de 700?C apresentaram estrutura cristalina. Os resultados de MEV evidenciaram a obten??o de p?s nanom?tricos. Os resultados de BET mostraram que os p?s obtidos apresentam ?rea superficial dentro da faixa utilizada em cat?lise (5-50m2/g). A caracteriza??o dos s?tios ativos foi realizada atrav?s da rea??o de dessulfuriza??o de tiofeno ? temperatura ambiente e a 200oC, com raz?o F/W igual a 0,7molh-1mcat -1. Os produtos da rea??o foram separados por cromatografia em fase gasosa e identificados por detec??o PFPD seletivo a enxofre. Todas as amostras apresentaram convers?o acima de 95%
