Resumo
The gadolinium-doped ceria nanorods (Gd(0.2)Ce(0.8)O(2-x) ) were synthesized by hydrothermal treatment. It was shown that the use of microwave heating during hydrothermal treatment decreases the treatment time required to obtain gadolinium-doped ceria nanorods and that oriented attachment is the dominant mechanism responsible for anisotropic growth. It was clear that Gd(0.2)Ce(0.8)O(2-x) nanorods were more catalytically active than commercial CeO(2) in the ethanol reforming reaction.
