摘要：

This article summarizes our recent developments for H2O2- and O-2-based green oxidation reactions by polyoxometalates (POMs) and related compounds. POM-based structurally controlled molecular catalysts exhibit high catalytic performance for epoxidation and sulfoxidation with H2O2. These molecular catalysts can be immobilized on the organic-inorganic hybrid support with covalently anchoring N-octyldihydroimidazolium cation fragments via the anion exchange. In addition, we have developed supported metal hydroxide catalysts such as Ru(OH)(x)/Al2O3 and Cu(OH)(x)/TiO2 on the basis of the information of the catalytically active sites with POMs. By using these supported metal hydroxide catalysts, novel aerobic oxidative synthesis of nitriles and amides, and efficient aerobic oxidative homocoupling of alkynes can be realized.
