Selective oxidation of aqueous organic pollutants over MOFs-based catalysts: A mini review

Efficient decontamination from water have attracted global attention in recent years. Advanced oxidation processes (AOPs) are widely used for aqueous organic pollutants degradation for water purification. However, it still is great challenge to efficiently oxidize the trace micropollutants especially from sewage matrix containing complicated matters, which would consume the reactive species to inhibit the decomposition of the target contaminants. Recently, many researchers devoted to the selective oxidation to address the above-mentioned problem. Various environmental functional materials like metal oxides and carbonaceous materials have been applied as catalysts for selective organic pollutants oxidation. Among them, metal–organic frameworks (MOFs) and their composites/derivatives displayed huge potential due to their designable structure and excellent catalytic performance. This review presented the research progress of MOFs-based materials in selective oxidation toward aqueous organic pollutants, in which some examples were analyzed in detail to show their performances, mechanisms as well as influence factors. The unique advantages of MOFs-based materials for selective oxidation were also discussed. Finally, the challenges and prospects of MOFs-based environmental functional materials in selective oxidation from water were proposed.
