摘要: Abstract Alloy catalysts of Pt 50 Au /Ce x C with various Ce additions ( ) were prepared for the oxygen reduction reaction (ORR). The characterization alloy structures, surface species, and electro-catalytic activities performed by XRD, temperature-programmed (TPR), rotating disc electrode (RDE) technique, respectively. ORR activity /C catalyst a promotion 15% CeO 2 was enhanced significantly in comparison to commercial Pt/C within mixed kinetic-diffusion control region. addition decreased particle sizes, increased dispersion segregation which resulting an moderate oxophilicity on catalysts.
