Abstract
Photoelectrocatalysis (PEC) is a promising approach that can convert renewable solar energy into chemical energy, while most concern is concentrated on PEC water splitting to obtain high-value-added fuel—hydrogen. In practice, more economic benefits can be produced based on PEC technique, such as H2O oxidative H2O2 synthesis, organic selective oxidation, organic pollutants degradation and CO2 reduction. Although there are plenty of excellent reviews focusing on the PEC water splitting system, the production of various high-value-added chemicals in PEC systems has not been discussed synthetically. This Account will focus on the production process of various high-value-added chemicals through PEC technology. The photoelectrode design, reaction environment and working mechanisms of PEC systems are also discussed in detail. We believe that this comprehensive Account of the expanded application of photoelectrocatalysis can add an inestimable impetus to the follow-up development of this technology.
