Abstract Developing a bifunctional water splitting catalyst with high efficiency and low cost are crucial in the electrolysis industry. Here, we report rational design simple preparation method of MoS 2 ‐based electrocatalyst on carbon cloth (CC). The optimized P‐doped @CoP/CC presents overpotentials for hydrogen (HER) oxygen evolution reactions (OER) 64 282 mV alkaline solution as well 72 HER overpotential H SO 4 at current density 10 mA cm −2 . Furthermore, P‐MoS delivered relatively cell voltages 1.83 1.97 V densities 500 30 % KOH. two‐electrode system showed remarkable stability h, even outperformed benchmark RuO ||Pt/C catalyst. excellent electrochemical performance can be credited to unique microstructure, surface area, synergy between metal species. This study possible alternative noble metal‐based catalysts overcome challenges industrial applications.
