Abstract

Two novel polyoxometalate-based catalysts were prepared by modifying Keggin POM H₄PMo₁₁VO₄₀ with a coumarin-surfactant through electrostatic interactions. The results indicate that (Coumarin)₃HPMo₁₁VO₄₀ exhibits excellent catalytic activity in the selective oxidation of benzyl alcohol using air as the oxidant, where the conversion of benzyl alcohol is 99%, and the selectivity for benzaldehyde is 100%. The excellent catalytic performance can be attributed to π-π* conjugate effects with the reactant, and the structural characteristics of the large BET specific surface area and pore size of the catalyst.
