Abstract

The transformation of visible light to electrical energy for the activation and functionalization of organic compounds, under the synergistic conditions of visible light and the photoelectric current, is an atom-economical, environmentally benign, self-powered, and interfacial enabling technology. Photoelectrocatalysis (PEC) enables selective chemical transformations under mild conditions via the generation of reactive intermediates. This catalysis process is advantageous in chemicals synthesis due to its broad functional group tolerance, site-specific selectivity, biocompatibility, and operational simplicity. Photoelectrode materials are applied as useful tools to perform organic oxidations and reductions for the chemical syntheses of important compounds. In this chapter, we summarize state-of-the-art applications of PEC in the synthesis of valuable chemicals and solar fuels. Specific prominence has been given to chemical transformations concerning C–H bond activation, and C–C and C–heteroatom coupling, whereby new chemical bonds are formed via late-stage functionalization of interesting compounds or coupling of two molecular building blocks. We also discuss challenges and future directions of PEC that will enable this technology to broaden its scope in chemicals synthesis.
