以MOFs为前驱体的多孔金属氧化物催化剂研究进展

多孔金属氧化物具有高比表面积、大孔径、特殊的形貌和结构特性,广泛应用于催化、锂离子电池、太阳能电池、气敏传感器等领域。金属有机骨架材料(MOFs)是一类具有周期性网络结构的新型多孔晶体材料,在气体存储、气体分离、催化等领域具有重要的应用价值。近年来,以MOFs为前驱体制备多孔碳和多孔金属氧化物成为MOFs应用领域一个新的研究热点。本文主要综述了以MOFs为前驱体制备的多孔金属氧化物和多孔金属氧化物/碳复合物在CO氧化、催化产氢、异丁烷脱氢、环已烯氧化、醇直接氧化为酯、醛氧化酰胺化反应、光催化降解有机物和氧还原反应等方面的应用。

Progress of porous metal oxide catalysts derived from MOFs

Porous metal oxides are used widely in catalysis, lithium ion battery, solar cell and gas sensor due to their high surface areas, large pore size, special morphology and structure characteristics. As a novel class of porous crystalline materials with periodic network structure, metal-organic frameworks (MOFs) are widely applied in gas storage, gas separation and catalysis. In recent years, the preparation of porous carbon and porous metal oxide using MOFs as precursors has become a new research hotspot in MOFs applications. This work reviews that porous metal oxides and metal oxides/carbon composites derived from MOFs are used as the catalysts for CO oxidation, hydrogen production, dehydrogenation of isobutane, oxidation of cyclohexene, direct oxidation of alcohols to esters, oxidative amidation of aldehydes, degradation of organic compounds and oxygen reduction.
