Abstract

The design of efficient and cheap electrocatalysts for the oxygen reduction reaction (ORR) plays a key role for renewable energy technologies such as fuel cells and metal–air batteries. Using a simple and effective route, electronically conductive acetylene black (AB) was deliberately introduced into Fe3O4/HCS-600 with enough ORR active sites to be used as an ORR catalyst. The good homogenization of the electron conductor AB and the high intimate contact of Fe3O4/HCS-600 and AB in the composite catalyst provide the possibility of facile electron accessibility. The resulting composite catalyst exhibited a high and stable electrocatalytic activity for the ORR, which is better than Fe3O4/HCS-600 or AB alone. These features may offer potential for the development of efficient ORR catalysts with low cost for alkaline fuel cells.
