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.
关键光催化反应中单原子提取光激发空穴
材料科学的最新进展导致单原子催化剂作为高效光催化剂的概念的出现,以优化太阳能转化为化学品/燃料的效率。经过50多年的研究,严重的电子-空穴复合仍然是制约光催化反应的关键瓶颈。特别是,缓慢的空穴萃取/迁移动力学严重抑制了电荷的分离/输运。因此,加速空穴转移动力学成为促进光催化过程的有效途径。然而,据我们所知,关于单原子提取光生空穴用于重要光催化反应的及时综述仍然缺失。因此,本文综述了单/双单原子光催化剂在关键的能量/环境相关反应(如水分解、二氧化碳还原、氮(N2)固定和废水处理/污染物降解)中空穴萃取的最新进展。本文特别介绍了先进的出/原位表征在探索电荷动力学中的重要作用。它还为精确设计先进的单/双单原子光催化剂提供了新的见解,优化了关键能源/环境相关应用的电子/空穴转移动力学。
