Polyoxometalate-based silica-supported ionic liquids for heterogeneous oxidative desulfurization in fuels

Abstract With the aim of deep desulfurization, silica-supported polyoxometalate-based ionic liquids were successfully prepared by a one-pot hydrothermal process and employed in heterogeneous oxidative desulfurization of various sulfur compounds. The compositions and structures of the hybrid samples...
