摘要: Abstract The inevitable corrosion of carbon support under operating condition direct methanol fuel cells significantly undermines the activity and durability Pt catalyst. Carbon-free materials with acceptable electronic conductivity, stability, co-functionality are promising alternative supports. We used poly(vinylpyrrolidone) as skeleton to prepare porous ceria for carbon-free support. has very high concentration oxygen vacancies, which plays key roles in: i) narrowing band gap improving conductivity; ii) catalytic performance. better electrooxidation achieved on supported
