Facile preparation of polyoxometalate nanoparticles a solid-state chemical reaction for aerobic oxidative desulfurization catalysis.

Polyoxometalate nanoparticles were synthesized a concise solid-state reaction method by directly grinding silver nitrate and the polyoxometalate (NH)HPMoVO at room temperature without the assistance of a surfactant. The as-prepared Ag(NH)PMoVO (AgPMoV) comprised uniform nanoparticles of 50 nm size, which provided significant catalytic oxidative desulfurization (CODS) performance using O, N + O or air as an oxidant. The high efficiency of 100% removal was obtained using AgPMoV nanoparticles as a catalyst in treating model refractory sulfurs.
