A Metal-Organic Frameworks Composite Catalyst Containing Platinum and Polyoxometalate for Direct Conversion of Methane

In this work, a novel heterogeneous compfosite catalyst was synthesized via the immobilization of platinum and polyoxometalate into MOFs containing bipyridine groups. The resulting UiO-67-Pt-Z has a high specific surface area (446 m(2) g(-1)), which is beneficial to adsorb more methane molecules in the methane catalysed transformation, and the homogeneous distribution of Pt and POM can improve the catalytic efficiency of the catalyst. Under mild reaction conditions, methanol, ethanol, and acetic acid can be obtained in 2 h. Our work provides a new catalyst for the rapid catalytic oxidation of methane to high value-added oxygenates and broadens new ideas for exploring effective methane direct conversion in future work.
