The invention relates to a preparation method and application of a Pd complex-phosphomolybdic acid one-component dual-active-center catalyst. Pd complexes and polyoxometalates are combined via electrostatic force, and a Pd complex-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 and easiness in implementation, operation controllability and the like. The Pd complex-phosphomolybdic acid binary catalyst represents better catalytic activity in the selective oxidation of alcohol, and the transformation ratio and selectivity respectively reach 99.8 percent and 98.2 percent to the hilt. |
