| Abstract: | "Four morphologies of metal-organic frameworks derived Mn(2)O(3) were prepared by calcination of metal-organic frameworks self-assembled from metal ions and organic ligands and loaded with platinum. The catalyst showed excellent catalytic performance for benzene (T(90%) = 131 degrees C). ESR (electron spin resonance) test showed that due to the strong electron metal support interaction between Pt and Mn(2)O(3), there were a large number of oxygen vacancies on the surface of the catalyst as active sites to promote the oxidation of benzene. The presence of a large number of Lewis acid sites on the catalyst surface was confirmed by Py-IP (Pyridine adsorption infrared spectroscopy) test. The intermediates of benzene catalytic oxidation are ethyl acetate, carboxylic acids and aldehydes, which can be verified by in-situ DRIFTS. In summary, the catalysts synthesized in this work provide a novel perspective for combining metal-organic frameworks-derived oxides and precious metals for the catalytic oxidation of volatile organic compounds" |
