Visible-light-driven photocatalytic selective organic oxidation reactions
Global energy and environmental demands continue to increase significantly. In recent years, visible-light-driven photocatalytic organic oxidation reactions have emerged as an alternative to traditional organic syntheses because they are economical, easily available, and afford superior selectivity. It is necessary to summarize the recent advances made in this research field, as well as provide an in-depth study into designing photocatalysts, particularly on the basis of mechanistic insight. Here, we focused on the most recent advances made in the visible-light-driven selective organic oxidation transformations and highlighted their reaction mechanisms. Moreover, the future development trend, challenges, and prospective outlook were discussed in detail. This review further made special emphasis on the more recent emerging concept according to which solar fuels and high-value-added chemicals could be simultaneously produced in a closed redox cycle. It can be predicted that more attention and achievements are expected on the simultaneous utilization of energetic electrons and holes via the integration of artificial photosynthesis coupled with organic oxidation reactions. Accordingly, we hope that this review will provide thoughts and guidance to rationally design heterogeneous photocatalysts for organic oxidation reactions, particularly considering mechanistic insights.
