The development of efficient, inexpensive, and stable hydrogen evolution reaction (HER) electrocatalysts is the key to large-scale water electrolysis technologies for hydrogen production. Constructing heterojunction electrocatalysts has become one of the effective strategies for designing high-performance HER electrocatalysts due to their unique heterogeneous interfaces. Herein, a new strategy of PH3 assisted synthesis of metaphosphate is reported, which is used to construct Co(PO3)2@NPC/MoS2 heterostructures (where NPC is N-doped porous carbon). The results show that the formation of Co(PO3)2@NPC/MoS2 heterogeneous interfaces can optimize the electronic structure of the electrocatalyst and greatly improve its HER performance. As a result, a lower overpotential of 119 mV at 10 mA cm-2 is obtained in alkaline electrolyte. This work provides a new perspective for the design of high-performance electrocatalysts for electrocatalytic water splitting. (c) 2021 Elsevier B.V. All rights reserved.
