The invention relates to a preparation method and application of a Pb complex-vanadate substituted phosphomolybdic acid one-component dual-active-center catalyst. Pb complexes and vanadate substituted phosphomolybdic acid are combined via electrostatic force, and a Pb complex-vanadate substituted phosphomolybdic acid binary catalyst is prepared in a one-pot way. The preparation method is based on coordination substitution and an ion exchange reaction, and has the characteristics of high simplicity, easiness in implementation, operation controllability and the like. The Pb complex-vanadate substituted phosphomolybdic acid one-component dual-active-center catalyst represents better catalytic activity in the selective oxidation of alcohol, and the transformation ratio and selectivity are respectively 92.8 percent and 93.2 percent. |
