Strategies and Challenges on Selectivity of Photocatalytic Oxidation of Organic Substances

Most organic compounds are conventionally synthesized under high temperature and elevated pressure, resulting in significant energy consumption wastage. Heterogeneous photocatalytic oxidation has the potential to provide a green route for synthesis of majority industrially important chemicals. The major limiting factor affecting efficiency is lack selectivity; therefore, substantial effort been devoted solving this problem. Responding fast-moving progress, review gives an overview fundamental understanding reactive oxygen species involved oxidations furthermore, general mechanisms few crucial reactions. focus critical on discussion diverse strategies improve selectivity value chemicals, including band engineering, metal loading, hybrid materials, defect with primary aim highlighting catalyst design protocols based reaction mechanism. Finally, difficulties challenges developing highly selective photocatalysts comprehensively discussed order help direct future research.
