Interfacial electronic structure engineering on molybdenum sulfide for robust dual-pH hydrogen evolution.

ABSTRACT: Molybdenum disulfide, as an electronic highly-adjustable catalysts material, tuning its electronic structure is crucial to enhance its intrinsic hydrogen evolution reaction (HER) activity. Nevertheless, there are yet huge challenges to the understanding and regulation of the surface electronic structure of molybdenum disulfide-based catalysts. Here we address these challenges by tuning its electronic structure of phase modulation synergistic with interfacial chemistry and defects from phosphorus or sulfur implantation, and we then successfully design and synthesize electrocatalysts with the multi-heterojunction interfaces (e.g., 1T_0.81-MoS₂@Ni₂P), demonstrating superior HER activities and good stabilities with a small overpotentials of 38.9 and 95 mV at 10
