Abstract In this work, reduced graphene oxide (rGO) with homogeneously dispersed phosphotungstate acid (HPW), were directly fabricated by using electrochemical strategy. In this one-pot route, the reduction of graphene oxide (GO) and HPW anchoring on rGO (HPW/rGO) have been achieved simultaneously. This strategy has not toxic reductants used, and meanwhile, produces high-quality rGO with sheet structure. Sheeted rGO could provide more anchor sites for HPW and prohibited HPW agglomeration. The produced HPW/rGO hybrid material performed high activity and durability in oxidative desulfurization (ODS) reaction due to the synergism of HPW and rGO. This work provides a novel sight for preparing high-efficient and stable catalyst for oxidative desulfurization.
