Recent Progress in Diamond-based Electrocatalysts for Fuel Cells

Attributed to highly stable structure of sp 3 hybridized carbon atoms, diamond has excellent physical and chemical stabilities.As new conductive diamond materials, boron-doped diamond (BDD) films and particles, as well as undoped nanodiamond (ND) has become the ideal support of the high stability electrocatalysts for fuel cells.Futher investigation showed that the activity and stability of electrocatalysts could be futher improved if the new diamond materials were properly processed.The doping treatment, including doping into diamond and the graphite structure from conversion of diamond, was used to produce diamond-based non-Pt electrocatalysts for fuel cells.It was considered that the sp 3 structure of diamond played a unique role in enhancing the stability of diamond-based non-Pt electrocatalysts.In this paper, related studies of diamond-based electrocatalysts were summarized for the references of future study.
