Electrodeposition of pure nanometric CeO 2 and Bi 2 O 3 thin films for electrodegradation of organic pollutants

Résumé

Pollution with different types is one of the major problems that threaten our planet. Very large amounts of pollutants are emitted worldwide and cause to the health of the humans and the environment, which will cause a decrease in resources for sustainable development of the planet. It is therefore essential to seek scientific solutions to reduce these hazardous emissions. In this context, the development of new materials to detect and clean up liquid and gas emissions from all sources is inevitable. The rare earth oxides have been used for many years to improve the reactivity, selectivity and stability of the catalysts. These oxides include cerium and bismuth oxide, which have been electrodeposited on several substrates under galvanostatic condition from aqueous solutions. The X-Ray diffraction (XRD) and scanning electron microscopy (SEM) studies revealed that as deposited films are nanocristalline, and the films are porous and the surface morphology changes with variation of several parameters (Current, substrate...).
