Application of Manganese Oxide Octahedral Molecular Sieves(OMS-2)in Clean Synthesis of Organic Compounds

The manganese oxide octahedral molecular sieve(OMS-2),because of its excellent oxidation,adsorption,ion-exchange,and conductivity properties,was wildly used in various fields such as environmental,semiconductor,synthetic organic.Because of the mixed valency in the framework and abundant surface defect vacancy,OMS-2 could effectively activate green oxidants such as oxygen and hydrogen peroxide,making it an effective heterogeneous catalyst and functional supporterin clean synthesis of organic molecules.Moreover,the OMS-2 catalysis material exhibited excellent activity,selectivity,and structural stability.We reviewed OMS-2 as heterogeneous catalyst and electron transfer medium(also as functional supporter in supported catalysts)in the clean oxidation synthesis of organic molecules.Finally,the existing problems and future development of OMS-2-catalyzed oxidations were summarized and proposed.
