Mechanochemical templated synthesis of mesoporous alumina-supported polyoxometalate catalysts toward selective oxidation of sulfides

Abstract

Polyoxometalates are important catalysts, but their low surface area and leaching in solutions present challenges. We developed a facile, green, solvent-free mechanochemical method to anchor polyoxometalates on mesoporous alumina. The resulting catalysts showed high activity, selectivity in sulfide oxidation, and reusability for at least seven cycles, achieving gram-scale reactions efficiently.
