With the gradual transition from traditional energy to clean energy, hydrogen energy has gradually entered people's vision. Hydrogen production and hydrogenation are typical atom-economic reactions and play an irreplaceable role in global economic growth, but they encounter huge challenges. Single-atom catalysts (SACs) show the highest atomic utilization and uniform active sites, which have broad development prospects in hydrogen production and hydrogenation. Herein, we systematically review the research progress on SACs in hydrogen production and hydrogenation, reveal the origin of the high catalytic activity of SACs on the atomic scale, propose strategies for strengthening the reaction process, and summarize the rational design principles for SACs for hydrogen production and hydrogenation. Lastly, prospects are given to the present opportunities, challenges, and applications of SACs in hydrogen production and hydrogenation reactions.

单原子制氢加氢催化剂的合理设计原则


随着传统能源逐步向清洁能源过渡，氢能源逐渐进入人们的视野。制氢和加氢是典型的原子经济反应，在全球经济增长中发挥着不可替代的作用，但也面临着巨大的挑战。单原子催化剂（SAC）具有最高的原子利用率和均匀的活性位点，在制氢和加氢方面具有广阔的发展前景。本文系统回顾了SACs在制氢和加氢方面的研究进展，揭示了SACs在原子尺度上高催化活性的根源，提出了强化反应过程的策略，总结了SACs制氢的合理设计原则和氢化。最后，对SAC目前在制氢和加氢反应中的机遇、挑战和应用进行了展望。
