Abstract
Carbon black that is introduced into Co3O4 will reduce the overpotential of the oxygen evolution reaction. By adding Au, the Co3O4/C catalyst exhibits superior electrochemical activity and excellent stability for the oxygen evolution reaction. The catalyst with a weight ratio of Au to Co3O4 of 1:3 gives the best performance. After loading with Au, the binding energy value of Co 2p has a positive shift, which will increase formation of CoIV cations of the active centers.Keywords
