Bimetallic sulfides with earth‐abundant transition‐metal elements are proposed to enhance the electrocatalytic activities. Further replacement of S atom by less electronegative P atom improves the electrocatalytic performance of OER and HER. Herein, hollow bimetallic zinc cobalt phosphosulfides (Zn 0.3 Co 2.7 S 3 P) are synthesized by a two‐step process. The optimal catalyst of Zn 0.3 Co 2.7 S 3 P with particle size of 50 nm displays an excellent electroactivity and long‐term durability toward efficient overall water splitting process in alkaline medium. The excellent bifunctional electrocatalytic performance may be ascribed to the synergistic effect of hollow structure, anion substitution tuning and unique size control.
