Oxidation/adsorption desulfurization of natural gas by bridged cyclodextrins dimer encapsulating polyoxometalate

► CDP was obtained by a bridged cyclodextrins dimmer encapsulating H9[P2Mo15V3O62]. ► The desulfurization efficiency of CDP can reach 99.6% after being used for 2 h. ► The desulfurization product from CDP mainly contained sulfur. ► The space velocity has little effects on sulfur capacity of CDP. ► CDP can be recycled five times with a slight decrease in desulfurization effect.
