Abstract
Recent advances on material science result in the emerging concept of single atom catalysts as highly efficient photocatalysts to optimize the conversion efficiency of solar energy into chemicals/fuels. After more than five decades of research, severe electron–hole recombination remains the key bottleneck restricting the photocatalytic reactions. Particularly, the sluggish hole extraction/migration kinetic seriously suppresses the charge separation/transport. Thus, accelerating hole transfer kinetics emerges as the effective route to boost the photocatalytic processes. Nevertheless, to the best of our knowledge, a timely review, which focuses on single atom extracting photogenerated hole for important photocatalytic reactions, is still missing. Thus, this review summarizes the latest achievement of hole extraction in single‐/dual‐single atom photocatalysts for key energy/environment‐related reactions (e.g., water splitting, Carbon dioxide (CO2) reduction, Nitrogen (N2) fixation, and wastewater treatment/pollutant degradation). Particularly, this review introduces the important role of advanced ex/in situ characterizations for exploring charge kinetics. It also offers new insights into accurate design of advanced single‐/dual‐single atom photocatalysts with optimized electron/hole transfer kinetics for key energy/environmental‐related applications.
