Polyoxotungstate ([PW₁₁O₃₉]^7-) immobilized on mesoporous polymer for selective liquid-phase oxidation of alcohols using H₂O₂.

ABSTRACT: Selective oxidation of alcohols is an attractive organic transformation and has received tremendous attention from the scientific community over the years. Herein, a mesoporous polymer (MP) was synthesized by a template-free solvothermal approach. The surface of the MP was functionalized with quaternary ammonium groups and polyoxotungstate anion (PW₁₁O₃₉ ^7-) was subsequently supported on the MP as a counter anion to the ammonium cation by a simple ion-exchange procedure. The structure of PW₁₁ and PW₄ complexes was confirmed by ³¹P NMR and FTIR analysis. The surface properties of all the catalysts synthesized were explored by various characterization techniques such as nitrogen sorption, TGA, contact angle measurement, and IC
