摘要：Currently, the construction of heterostructures to optimize electrocatalytic activities is a hot research topic, since there is still a certain gap between the electrocatalytic properties of these heterostructures and that of Pt/C. With this in mind, we utilized in-situ vapor-phase phosphorization-sulfurization to obtain the CoP3/MoS2-Co0.75Mo3S3.75 (CoP/CoMoS, for short) heterostructure on carbon cloth (CC), which exhibits Pt-like electrocatalytic performance and excellent stability in acid electrolyte. Activated by CoP3 active phase, the electronic configuration of CoMoS and the adsorption energy of H* (G(H*)) are greatly optimized. Meanwhile, the rapid oxidation of CoMoS phase can be effectively avoided under the protection of CoP3 layer. This work provides a reference for the design of heterostructures and their mechanism of action in electrocatalysis.
