Abstract	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. All rights reserved.
