Regulating Local Atomic Environment around Vacancies for Efficient Hydrogen Evolution

ACS Nano, Journal Year: 2024, Volume and Issue: 18(14), P. 10312 - 10323

Published: March 27, 2024

Defect engineering is essential for the development of efficient electrocatalysts at atomic level. While most work has focused on various vacancies as effective catalytic modulators, little attention been paid to relation between local environment and activities. To face this challenge, we report a facile synthetic approach manipulate environments in MoS2 with tunable Mo-to-S ratios. Our studies indicate that more Mo terminated exhibits better hydrogen evolution reaction (HER) performance than S defect-free MoS2. The improved originates from adjustable orbital orientation distribution, which beneficial regulating H adsorption eventually boosting intrinsic per-site activity. This uncovers underlying essence catalysis provides significant extension defect rational design transition metal dichalcogenides (TMDs) catalysts beyond.
