Pełny tekst źródłaThe interaction of water with actinides oxide surfaces remains poorly understood. The adsorption of water on PuO2 surface and (U,Pu)O2 surface leads to hydrogen generation through radiolysis but also surface evolution.The study of water interaction with mixed oxide (U,Pu)O2 and PuO2 surfaces requires the implementation of non intrusive techniques. The study of the hydration of CeO2 surface is used to study the effectiveness of different techniques. The results show that the water adsorption leads to the surface evolution through the formation of a hydroxide superficial layer. The reactivity of water on the surface depends on the calcination temperature of the oxide precursor. The thermal treatment of hydrated surfaces can regenerate the surface. The study on CeO2 hydration emphasizes the relevancies of these techniques in studying the hydration of surfaces.The hydrogen generation through water radiolysis is studied with an experimental methodology based on constant relative humidity in the radiolysis cell. The hydrogen accumulation is linear for the first hours and then tends to a steady state content. A mechanism of hydrogen consumption is proposed to explain the existence of the steady state of hydrogen content. This mechanism enables to explain also the evolution of the oxide surface during hydrogen generation experiments as shown by the evolution of hydrogen accumulation kinetics. The accumulation kinetics depends on the dose rate, specific surface area and the relative humidity but also on the oxide aging. The plutonium percentage appears to be a crucial parameter in hydrogen accumulation kinetics

Pełny tekst źródłaNowadays, environment pollution and energy crisis are widely concerned all over the world. It is an urgent task to develop environment-friendly technologies for alternative clean energies. Photocatalysis is one of the most promising methods for such subjects. The most used semiconductor in photocatalysis is TiO₂ due to its excellent physical and chemical properties, high availability and low cost. The modification of TiO₂ with metal nanoparticles has demonstrated have a beneficial effect in the photocatalytic activity of TiO₂.Identifying the factors that govern the kinetics of the photocatalytic processes and understanding the role that metal nanoparticles play is inherent to achieve the desired goal of developing more efficient photocatalytic systems.Although great strides have been made in the study of the effect of surface modification of TiO₂ with mono- and bimetallic NPs on its photocatalytic activity, a lot still remains unknown. Most of the investigations have been based on the study of kinetics or mechanisms involved in photocatalysis. There are few reported studies, which integrate the absorption, dynamics of charge carriers and photocatalytic activity.The later has motivated the development of the present work, having the main objective to study systematically the effect of metal NPs on titania surface in the three principals steps of the photocatalytic processes: (1) absorption of light (generation of electron-hole pair), (2) dynamic of charge carriers, and (3) efficiency of the photocatalytic activity

Pełny tekst źródłaActinide oxides are hygroscopic materials. The adsorption of water on their surfaces is likely to cause changes in the nature or condition. In the case of oxides with a high dose rate, the effects of radiolysis of the water causes the decomposition of water and generates hydrogen. These two aspects: surface study and radiolysis of water have been studied here.The study of the generation of dihydrogen by radiolysis of water adsorbed on the surface has shown that this linear generation in the early stages reaches a stable concentration after several hours. This stationary state has been very little observed, and is absent in the case of significant humidity. Conditioning in a dihydrogen-containing atmosphere made it possible to highlight a reaction of consumption of dihydrogen by the material. These experiments led to the emergence of a kinetic model based on two reactions of production and consumption of dihydrogen. The first corresponds to the decomposition of the water under the effect of the radiation, and for the second it is suspected a partial reduction of the surface with the formation of a sub-stoichiometric phase on the surface, however no technique of analysis of surface has not formally highlighted this phase.Inverse gas chromatography is a technique that is not very intrusive with respect to the adsorbed water layers because of the temperatures and pressures involved and the absence of energy deposition. This technique has been used on oxides of thorium and uranium. On thorium oxide, this results in an impact of the calcination temperature, with a maximum of surface energy for calcination at 650 ° C. In addition, it has been shown that the preparation of thorium dioxide can impact the state of its surface. Indeed, it has been observed dehydration of thorium oxalate over time, impacting the structure of the latter. This modification affects the surface of the final oxide by a drop-in surface energy and a change in the distribution of surface adsorption sites. Nevertheless, a chemical treatment of oxalate makes it possible to recover the surface reactivity and a distribution of the adsorption sites. The hydration of the surface shows an increase in surface energy, but this increase is observed only for hydrations of long duration.Keywords: water sorption, radiolysis, plutonium, inverse gas chromatography, thorium, uranium

Pełny tekst źródłaSupercapacitors based on ionic liquid (IL) as electrolyte and graphene as electrode are promising devices. They have a large number of charge-discharge cycles much faster than the current batteries but suffer from low energy storage density. The addition of gold nanoparticles between graphene sheets and IL appears promising to improve their performances. We use the Langmuir film method, a procedure for studying layers and interfaces on a water surface under various physico-chemical conditions, to study the graphene oxide (GO)/IL interface. We use the ionic liquid [C20mim]+[NTf2]- and graphene oxide (capable of forming a stable film on the surface of the water). We use irradiation of the surface by X-rays coupled with the addition of HAuCl4 3H2O gold salt in the sub-phase to form by radiolysis gold nanoparticles under the organic film. The objective of this thesis is to study the formation of the interface between graphene oxide and ionic liquid without and in the presence of gold nanoparticles at the interfaces. In this goal, we use a solvent common to both species: NMP. Then, depositing the film on a sub-phase formed by a solution of gold, we use surface radiolysis by X-rays to form gold nanoparticles in contact with this film. We therefore first studied the influence of the solvent NMP on pure films of ionic liquid and graphene oxide. We have demonstrated the presence of residual NMP in the IL film that influences the formed structures. NMP was shown to be a solvent capable of forming a stable film of graphene oxide at the air/water interface. Thus, the NMP will be considered in the organization of the interfaces for the mixed film. We then studied the mixed films of IL and GO. We showed that the organization of the IL depended on the nature of the two interfaces surrounding its monolayer. At low surface pressure, the GO sheets partially cover the IL monolayer adsorbed to the water surface. IL monolayer is in a disorderly phase whether or not it is covered by GO sheets. At high pressure, part of the IL migrates above the GO sheets. We see a coexistence between two structures formed by the IL, a hexagonal 2D monolayer structure and a multilayer structure organized in a monoclinic network. We then used surface radiolysis to form gold nanoparticles in contact with the organic film. The sub-phase used is then a solution of gold ions. We show that there are two regimes depending on the quantity of gold in the sub-phase. For a quantity of gold ions less than 500 times that of IL molecules deposited on the surface, we observe the formation of gold nanoparticles. For a quantity of gold greater than or equal to 500 times the quantity of molecules of IL, the formation of gold nanoparticles takes place only at surface pressures lower than that of the collapse of the film. Above this surface pressure, we no longer observe the formation of gold nanoparticles but the appearance of a triclinic structure. This results from the substitution of the anion of the IL by the gold ion. Finally, we studied the effects of irradiation on a mixed GO-IL film deposited on a gold solution. The film adopts a combination of the behaviors observed on mixed IL-GO films deposited on water and pure IL and OG films on gold solution. At low pressure, we find the structural behaviour observed on pure water but the presence of residual NMP induces the formation of gold nanoparticles. At high pressure, IL molecules no longer cover GO sheets. We observe the appearance of the triclinic structure as well as gold nanoparticles always attributed to the presence of residual NMP
