AbstractFacing the complex application environment and overall inefficiency in the complete water‐splitting process, the development of highly efficient and stable catalytic materials is urgently required. This study innovatively proposes and for the first time implements a rapid synthesis technique driven by microwave‐induced sulfur sublimation, successfully preparing MS2/RuS2 (M = Co, Fe, Ni) heterostructure interfaces with high structural stability and uniform active site distribution within merely 60 s. By incorporating iron‐group sulfides, the electronic structure of pyrite‐type RuS2 is effectively modulated, enabling the developed MS2/RuS2@G catalyst to exhibit superior activity in alkaline environments. Particularly, the cobalt‐based sulfide regulated pyrite‐type RuS2 (CoS2/RuS2@G) achieves a mass activity in the hydrogen evolution reaction (HER) that is 15.4 times that of 20 wt.% Pt/C, and in the oxygen evolution reaction (OER), it surpasses commercial IrO2 by two orders of magnitude. This research not only provides a new pathway for enhancing the performance and environmental adaptability of water‐splitting catalysts but also presents a simple and universal method to boost catalytic activity through a synergistic modulation strategy.
