Special Issue Information

Dear Colleagues,

Selective oxidation is an important class of chemical reactions that holds a crucial position within today’s chemical industry processes. In recent years, significant advances have been made in this field, and new trends have subsequently emerged.

The development and application of selective oxidation catalysts are key processes within this field. The rapid development of controllable synthesis and characterization techniques for catalytic new materials, such as single atoms, diatoms, clusters, etc., has provided an important foundation for the design and preparation of selective oxidation catalysts with spatially separated active centers. Additionally, the progress in the development of several other new catalytic materials has brought new insights and breakthroughs regarding the catalytic selective oxidation process.

Photocatalysis or electrocatalysis methods offer new opportunities in the field by generating highly reactive oxygen species or directly activating reactants under mild conditions. The introduction of photocatalytic and electrocatalytic systems has facilitated the construction of new selective oxidation systems.

Ideas such as replacing organic peroxides with air/oxygen/hydrogen peroxide as oxidants and replacing organic solvents with water have become major trends in selective oxidation catalysis research. Selective oxidation of low-carbon hydrocarbons such as methane, epoxidation of propylene, phenol production from benzene, and selective oxidation of biomass represent the most challenging problems in this field.

Methane is an abundant and relatively clean fossil fuel resource; therefore, its utilization as a chemical feedstock has a major impact on the chemical industry. However, its inert nature makes direct conversion into value-added products difficult under mild conditions. Compared to the gas-phase selective oxidation of methane, there have been several recent advances in the liquid-phase conversion of methane. This review categorizes the reports on the liquid-phase selective oxidation of methane according to the solvent and oxidant used. The advantages and disadvantages of each approach are discussed. High yields of methyl bisulfate as a methanol precursor can be achieved using SO3 in sulfuric acid; however, more attention should be paid to the separation process and overall economic analysis. However, the aqueous-phase selective oxidation of methane with in situ generated H2O2 is quite promising from an environmental point of view, provided that an economical reducing agent can be used. Based on the current state-of-the-art on this topic, directions for future research are proposed. Full article
