The key to electrolytic water includes two half-reaction processes: hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Transition metal phosphides (TMPs) are a class of prospective bifunctional electrocatalysts, but their performances are still far from the commercial catalysts. In this work, we design several kinds of Ni₂P@CoP hetero-structured catalysts by the modification of Ru atom. The 0.1Ru-Ni₂P@CoP catalyst presents the overpotentials of 82.7 (HER) and 245.3 mV (OER) at 10 mA/cm² in 1 mol/L KOH solution. Moreover, it effectively promotes water splitting under alkaline conditions (ƞ₁₀ = 1.21 V) and seawater conditions (ƞ₁₀ = 1.13 V). The surface self-reconfiguration also makes it remain stable under prolonged cycling in both electrolytes. Density functional theory (DFT) calculations further indicate that doping engineering and heterostructures cause electronic modulation and electron transfer thereby increasing the intrinsic activity of the catalyst.
