Novel synthesis of cone-like nanocomposite vanadium containing phosphomolybdovanadate@polyvinyl alcohol for oxidative desulfurization of gasoline

To preparation of clean gasoline fuel our group synthesized a novel nanocatalyst by supported phosphomolybdovanadate on polyvinylalcohol (PVA) as an organic polymer. Organic polymers are suitable candidates as matrices for assembling polyoxometalates. Hence in this work, PVA is used to play this important role as great matrices. (N(tBu)4)4HPMo10V2O40 (PMoV) was synthesized as our main polyoxometalate and then introduce PVA as polymer substrate. The structures of nanocomposite POM/PVA are characterized by FT-IR, UV-Vis, XRD and SEM. (N(tBu)4)4HPMo10V2O40/PVA nanocomposite was shown be able to scavenge mercaptans and hydrogen sulfide (with high yield) in gasoline by H2O2 as an oxidant.
