Item Acesso aberto (Open Access) Estudo do crescimento de nanofitas de céria dopada com gadolínio por sistema de aquecimento por micro-ondas(2013-09) GONÇALVES, Rosana de Fátima; CASTRO, D. A.; SANTOS, Maria Rita de Cássia; FIGUEIREDO, Alberthmeiry Teixeira de; BARRADO, Cristiano Morita; LEITE, Edson Roberto; GODINHO JÚNIOR, MarioCerium oxide (ceria) has attracted attention because of its important applications such as solid oxide fuel cells, catalysts for automobile exhaust gas, catalysts to obtain hydrogen, UV blockers, biomaterials, etc.. Control methods for synthesis of ceria are of great importance to explain or predict these properties. Thus, the objective of this work was to study the growth of cerium oxide nanobelts in a microwave-assisted hydrothermal system, where in 8 min 330 nm nanobelts were obtained at 130 ºC and 3 atm. The results collaborate to the research on reformers for ethanol and/or solid oxide fuel cells anode.
