| 英文摘要 | The oxygen reduction reaction is an important cathode reaction, thus seeking for low cost and high activity catalysts is highly demanded. Herein, a ternary catalyst composed of Co2P nanoparticles, N and P co-doped carbon (NPC) and CeO2 nanosheets (Co2P-NPC-CeO2) is reported for efficient oxygen reduction. In such composite, CeO2 nanosheets are coated with a carbon layer derived from dopamine, and then decorated with Co2P nanoparticles by using phytic acid as the phosphorus source. High ORR catalytic activity was achieved in the optimized sample with a high onset potential of 880 mV (vs RHE), a positive half-wave potential of 827 mV (vs RHE), a diffusion limited current density of 5.24 mA cm(-2), and a good durability (the half-wave potential exhibited almost 0 mV after 1000 cycles). Together with the good durability and methanol tolerance, the composite catalyst demonstrated here can be potentially applied in energy conversion devices. (C) 2019 Elsevier B.V.
