Abstract

Trifunctional catalysts for simultaneously generating H2, O2 and H2O provide a crucial means for improving the overall efficiency of H2O electrolysis. A series of nonnoble metal [M = Fe(III), Co(II), Ni(II)]-nitrogen co-doped oxidized graphite rods (M-N/OGR) that function as in situ working electrodes for tri-functional oxygen evolution reaction, hydrogen evolution reaction, and oxygen reduction reaction electrocatalysis was prepared. The enhanced performance of the hybrid catalysts appear mostly associated with dual active site mechanisms originating from the synergic effects of M-N/Co-doped on the surface of the OGR. The development of multifunctional electrocatalysts with optimal catalytic activity using transition metals and nitrogen doped OGR opens new fields for in situ synthesized electrocatalysts for use in clean electrochemical energy storage and conversion technologies.
