The study used a tungsten doping strategy to stabilize manganese-based bimetallic phosphide (W-CoMnP), effectively inhibiting the Mn³⁺ disproportionation and Mn²⁺ dissolution caused by the Jahn-Teller effect, and significantly improving the electrocatalytic activity and stability. The material exhibited excellent HER (η₁₀ = 95 mV) and OER (η₅₀ = 225 mV) performance, and achieved efficient and stable hydrogen evolution at 1.52 V in the AEM water electrolyzer, demonstrating its broad prospects in practical applications.
