MOFs热解制备新型Co基纳米材料及催化氧化性能研究

Aiming at the problems of low catalytic efficiency, high energy consumption and serious pollution that the petrochemical industry are facing, we propose a fundamental investigation on the preparation and catalytic oxidation performance of novel Co-based nano-materials deriving from thermolysis of MOFs, for the significant catalytic oxidation processes (e.g., cyclohexane oxidation for the synthesis of cyclohexanone/cyclohexanol, and alcohols aerobic oxidation to aldehydes/ketones/esters) in the petrochemical industry. The proposed work will focus on: (a) elucidate the structure-property relationship between the compositions, textural properties and pyrolysis conditions of MOFs, and the compositions, morphology, catalytic oxidation performance and stability of the formed nano-materials, and explore the formation mechanism of metal-based nano-materials from thermolysis of MOFs; (b) prepare novel Co-based nano-materials deriving from MOFs with high reactivity and stability for the typical catalytic oxidation reactions under environmentally friendly conditions, and develop a new catalytic oxidation methodology with the novel catalysts as the core technology. The proposed study will provide new theories and technologies to significantly improve the catalytic efficiencies for the cyclohexane oxidation to cyclohexanone/cyclohexanol and the oxidation of alcohols to aldehydes/ketones/esters compounds using the novel Co-based nano-materials deriving from MOFs, which has both scientific significance and application values.
