Abstract: Selective oxidation is an important type of chemical reactions and is playing vital roles in the chemical industry. Following the changing trend in resources and the requirements from sustainable and green chemistry, the pursuit of 100% selectivity to abate CO2 emission, the substitution of deplete resources with abundant or renewable ones, the use of air/O2/H2O2 as an oxidant instead of organic peroxides and the use of H2O to replace organic solvents have become major research directions in selective oxidation catalysis. The selective oxidation of methane and other alkanes, the epoxidation of propylene and the oxidation of benzene to phenol remain as the most challenging subjects in selective oxidation catalysis. The selective oxidation of specific functional groups in biomass-derived molecules has become a new growing research direction. The harnessing of photocatalysis and electrocatalysis has offered new opportunities for selective oxidation catalysis. This article highlights recent advances in selective oxidation of lower alkanes, in particular methane, epoxidation of propylene, benzene to phenol and selective oxidation of biomass-derived molecules. The key factors that control the catalytic activity and selectivity, and the fundamental issues related to active sites and reaction mechanisms for selective oxidation are discussed. This present article also touches new catalytic materials and methods for selective oxidation, and provides perspectives for future studies in the area.
