Electronic metal-support interaction (EMSI) offers a revolutionary strategy for designing high-performance electrocatalysts by precisely modulating interfacial electron transfer dynamics. Herein, we construct a Ru-loaded tungsten-molybdenum bimetallic phosphide heterostructure (Ru/WP-MoP) through EMSI engineering, which demonstrates exceptional hydrogen evolution reaction (HER) performance across pH-universal electrolytes. The optimized catalyst presents a remarkably low overpotential of 40 mV at 10 mA/cm² in alkaline media, outperforming Ru/C (η₁₀ = 52 mV). Remarkably, it retains significant activity even under acidic conditions (η₁₀ = 55 mV) and alkaline seawater (η₁₀ = 42 mV). In alkaline media, it operates continuously at 200 mA/cm² for 55 h with current density decay of less than 2%. Combined X-ray photoelectron spectroscopy analysis reveals that the strong EMSI effect induces electron transfer from WP-MoP to Ru, optimizing the d-band center position and reducing the water dissociation energy barrier compared with monometallic counterparts. This work establishes a general paradigm for developing robust transition metal phosphide catalysts via interfacial electronic structure manipulation, particularly for industrial-scale seawater electrolysis applications.
