Preparation and Oxygen Reduction Properties of Cu-N Co-doped Carbon-Based Catalysts

In order to solve the problems of high cost and poor stability of fuel cell cathode catalysts, Cu, N co-doped carbon based catalyst (Cu-N-KB) was prepared by simple heat treatment using alpha-nitroso-beta-naphthol copper, melamine and conductive carbon black. The characterization results show that Cu and N are uniformly distributed in the carbon support and the copper exists in the form of crystalline copper particles and amorphous Cu-N-x, The high specific surface area and mesoporous structure of the catalyst ensure a large number of active sites and fast mass transfer efficiency. The catalyst exhibits excellent oxygen reduction catalysis, methanol resistance and stability in an alkaline medium compared to commercial Pt/C catalysts.
