二硒化钼纳米催化剂的相调控与析氢研究进展
Recent advances in phase regulation and hydrogen evolution over molybdenum diselenide nanocatalysts
摘要
Abstract
Molybdenum diselenide(MoSe2)has emerged as a highly promising candidate to replace precious metal catalysts,owing to its tunable electronic structure and outstanding activity for the hydrogen evolution reaction(HER).This review systematically summarizes recent advances in the phase engineering of MoSe2 nanocatalysts,with the focus on seven major strategies—Hydrothermal/solvothermal methods,doping,selenization,chemical vapor deposition,metal induction and calcination,and their roles in promoting the transition from the semiconducting 2H phase to the metallic 1T phase,as well as the associated mechanisms underlying the enhanced HER performance.Studies have shown that optimizing the synthesis parameters,introducing heteroatoms,or constructing composite interfaces can effectively increase the 1T-phase content,electrical conductivity,and active sites,thereby significantly improving the catalytic activity and stability.Despite notable progress in phase-controlled synthesis,practical application is still limited due to the metastable nature of the 1T phase and challenges in scale-up.Future research should focus on developing synergistic regulation strategies that are of low-temperature,rapid,and in-situ.Coupling these approaches with advanced in-situ characterization and theoretical calculations will be crucial to unravel the phase transition mechanisms and interfacial synergy.Such developments are expected to pave the way for the application of MoSe2-based catalysts in practical hydrogen production,and the advancement of hydrogen economy.关键词
