Abstract Orbital hybridization is a promising approach to modulating the electronic structure of designed electrocatalysts boost reaction kinetics. In contrast d‐d hybridization, p‐d orbital between p‐block elements and d‐block metals can provide new opportunities modulate properties thus promote catalytic performance. Herein, phosphorus‐doped osmium (P‐Os) catalyst through ultrafast (20 s) microwave plasma engineering. Theoretical calculations verify d‐p P Os, leading modulation d‐band center Os active site. Specifically, neighboring exhibit highest activity, facilitating crucial processes such as H 2 O/H* adsorption dissociation. The overpotential P‐Os in alkaline seawater only 152 mV at 1 A cm −2 , which superior reported electrocatalysts. Moreover, synthesized catalysts are integrated into an anion exchange membrane (AEM) electrolyzer, demonstrating remarkable AEM electrolyzer requires 1.86/2.02 V achieve 500/1000 mA current densities. Then, achieved have great potential for practical electrocatalytic water‐splitting applications.
