摘要

Hydrogen is widely believed to be a promising fuel to solve the globalenergy crisis and environmental issues. The catalytic system representedby metal-supported catalysts is an important process of upgrading thehydrogen source in industry. Single-atom catalysts (SACs), which inheritthe advantages of homogeneous and heterogeneous catalysts, providea broad prospect for low-cost H_2 production technology. This reviewfocuses on the potential mechanisms in the rational design of SACs,including active sites, coordination configuration, mass loading, heteroatom-doping, and metal?support interaction. The design strategies ofsingle metal atoms on different supports are reviewed to give a proposalon how to immobilize the atomic active sites and modulate the geometric/electronic structures of SACs. Subsequently, the synergistic effectin SACs and the dynamic evolution of the atomically dispersed heterometalcatalysts are introduced, aiming to provide further guidelines forH_2 evolution SACs. H_2 generation from the water?gas shift reaction andelectro-/photocatalytic water splitting are the main research directionsat present. The latest progress of SACs employed in these applicationsis thoroughly reviewed. At the end of this review, personal perspectiveson the prospects and challenges of H_2 evolution SACs are put forward,hoping to promote the rapid development of SACs toward superior H_2evolution performance.
