Description

technical field [0001] The invention belongs to the technical field of preparation of alcohol oxidation catalyst materials, and relates to the preparation technology of a barium-silicotungsten oxide cluster catalyst, which lays the foundation for its catalytic application. [0002] technical background [0003] Since the 1970s, since the industrialization of silicotungstic acid catalyzed hydration of propylene to isopropanol has been realized, the research on metal oxygen cluster compounds has attracted widespread attention at home and abroad. Then, it reported [VO(H 2 O) 5 ]H[PMo l2 o 40 ] Catalyze the nitration reaction of alkanes. The research on the catalytic properties of POMs by many academic and industrial scholars has greatly promoted the development of metal oxygen cluster catalysis science and technology. [0004] Alcohol catalytic oxidation reactions play a very important role in daily chemical production. Because its corresponding product aldehydes or ketone...
