Visible-light photocatalysis and electrocatalysis are two powerful strategies for the promotion of chemical reactions that have received tremendous attention in recent years. In contrast, processes that combine these two modalities, an area termed electrophotocatalysis, have until recently remained quite rare. However, over the past several years a number of reports in this area have shown the potential of combining the power of light and electrical energy to realize new catalytic transformations. Electrophotocatalysis offers the ability to perform photoredox reactions without the need for large quantities of stoichiometric or superstoichiometric chemical oxidants or reductants by making use of an electrochemical potential as the electron source or sink. In addition, electrophotocatalysis is readily amenable to the generation of open-shell photocatalysts, which tend to have exceptionally strong redox potentials. In this way, potent yet selective redox reactions have been realized under relatively mild conditions. This Perspective highlights recent advances in the area of electrophotocatalysis and provides some possible avenues for future work in this growing area.
可见光光催化和电催化是近年来备受关注的两种促进化学反应的强大策略。相比之下,将这两种模式结合起来的过程,即光电催化,直到最近仍然相当罕见。然而,在过去的几年中,该领域的一些报道表明,结合光和电能的力量来实现新的催化转化是有潜力的。光电催化通过利用电化学电势作为电子源或受体,无需使用大量化学计量或超化学计量的氧化剂或还原剂来进行光氧化还原反应。此外,光电催化很容易适应开壳层光催化剂的生成,开壳层光催化剂往往具有异常强的氧化还原电位。通过这种方式,可以在相对温和的条件下实现有效的且选择性的氧化还原反应。本综述重点介绍了光电催化领域的最新进展,并为该不断发展的领域的未来工作提供了一些可能的途径。
