基于过渡金属二硫族化物析氢催化的研究进展

To solve the global climate change and energy crisis, one of the most effective alternative energy sources is hydrogen(H₂). Hydrogen evolution reaction(HER) is regarded as green process for the sustainable production of hydrogen, usually requiring a catalyst to reduce the electrochemical potential and improve the conversion efficiency. Currently the most advanced catalyst still relies on precious metals. Recent research shows that the transition metal dichalcogenides(TMDs) also has excellent catalytic activity. Comparing to precious metals, TMDs are expected to be the alternatives to precious metals in the field of catalysis. Based on this, this review discusses the researches of TMDs in hydrogen evolution reaction in recent years and strategies to improve catalysis activity, including atomic engineering, phase engineering and heterogeneous junction. Finally, the challenges and opportunities of TMDs catalytic materials are concluded.
