摘要：Heteroatom (B, N) co-doped three-dimensional (3D) porous graphitic carbon made from methyl violet and boric acid are fabricated via a super simple synthesis using silicon sphere as the hard-template. The 3D structure of as prepared samples are analyzed by TEM, XRD and XPS. As resulted, the activity of BNC-800-800 in ORR and OER is better than sole-doped (NC-800) and dual-doped (NPC-800) hybrids. The strong synergistic effect with 3D porous structure, dual doping and high amount of pyridinic and pyrrolic nitrogen endows BNC-800 catalyst with an outstanding activity toward ORR and improved OER performance to commercial Pt/C catalyst under alkaline condition.
