Description

technical field [0001] The invention belongs to the technical field of preparation of multi-metal oxygen cluster catalyst materials, and relates to the preparation technology of a binuclear magnesium-germanium tungsten oxygen cluster catalyst, laying the foundation for its catalytic application. [0002] technical background [0003] The development of polymetallic oxygen cluster chemistry has experienced nearly two hundred years of history, and has become one of the fastest-growing and most interdisciplinary fields in current inorganic chemistry. Early polymetallic oxygen cluster chemistry believed that inorganic oxyacids (such as phosphoric acid, sulfuric acid, tungstic acid, molybdic acid, etc.) could be condensed to form condensed acids. Polyoxometallic cluster chemistry is about the chemistry of isopolyacids and heteropolyacids. The former involves isopolyanions and the latter involves heteropolyanions. In polymetallic oxygen clusters, tungsten can form many isopoly and...
