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 CoP 3 /MoS 2 −Co 0.75 Mo 3 S 3.75 (CoP/CoMoS, for short) heterostructure on carbon cloth (CC), which exhibits Pt‐like electrocatalytic performance and excellent stability in acid electrolyte. Activated by CoP 3 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 CoP 3 layer. This work provides a reference for the design of heterostructures and their mechanism of action in electrocatalysis.
