沿着人们对有机合成中的绿色和可持续发展的探索兴趣日益浓厚，光子作为最清洁的能量形式，已被广泛用于驱动各种有机转化。与利用均相光敏剂和光催化剂的成熟的有机光催化剂相比，固态半导体在该领域中受到较少但迅速增长的关注。本文综述了近年来有机光催化剂的研究进展，包括金属氧化物、金属硫族化合物和无金属碳氮化物。对于每一类半导体，首先介绍氧化和还原有机反应，然后是利用激发电子和空穴的氧化还原偶联反应。最后，讨论了该领域面临的挑战和未来的机遇。(C)2020爱思唯尔有限公司版权所有
Along with the increasing interest in exploring green and sustainable approaches in organic synthesis, photon, the cleanest energy form, has been widely utilized in driving various organic transformations. In contrast to well-established organic photocatalysis utilizing homogeneous photosensitizers and photo-catalysts, solid-state semiconductors have received less but rapidly growing interest in this field. Herein, we summarize recent development in organic photocatalysis utilizing semiconductor-based photocatalysts, including metal oxides, metal chalcogenides, and metal-free carbon nitrides. For each category of semiconductors, both oxidation and reduction organic reactions are introduced first, followed by redox coupled reactions utilizing both excited electrons and holes. At the end, the remaining challenges and future opportunities of this field are discussed. (C) 2020 Elsevier Ltd. All rights
