As a clean energy source, water splitting can produce both hydrogen and oxygen, so it is significant to design high performance bifunctional electrocatalysts to improve the reaction efficiency, but remains a challenge. Herein, a Co 3 V 2 O 8 /MoS 2 / carbon cloth (Co 3 V 2 O 8 /MoS 2 /CC) composite was prepared by two‐step hydrothermal growth of Co 3 V 2 O 8 /MoS 2 on carbon cloth. This nanocomposite exhibited highly efficient electrocatalytic properties in both hydrogen evolution reactions and oxygen evolution reactions. When the current density reached 10 mA cm −2 , it merely required the overpotentials of 98 mV and 259 mV, respectively. Moreover, at a two‐electrode system, we measured the performance of Co 3 V 2 O 8 /MoS 2 /CC acted as both anode and cathode, and the current density could achieve 10 mA cm −2 with the voltage of only 1.62 V.
