Dicationic Ionic Liquid Modified Peroxophosphotungstate Encapsulated in Ordered Macro‐Microporous 3DOM‐ZIF‐8 for Ultra‐Deep Desulfurization of Simulated Fuel
Three-dimensionally ordered macro-microporous 3DOM-ZIF-8-based peroxophosphotungstate (DIL-PW<sub>4</sub>) is constructed to break the limitation of micropores inherent in traditional supported catalysts. The presence of ordered macropores expose more active sites and significantly enhance mass diffusion, thereby boosting catalytic activity, especially in reactions involving larger molecules. The prepared composite DIL-PW<sub>4</sub>@3DOM-ZIF-8 is verified by various characterization techniques and used as a catalyst for the extraction oxidation desulfurization of multi-component simulated fuel. The results showed that heterogeneous catalyst DIL-PW<sub>4</sub>@3DOM-ZIF-8 has a remarkable catalytic effect, with 97.03% total sulfides removal in 120 min. In addition, the stability and reusability of the catalyst DIL-PW<sub>4</sub>@3DOM-ZIF-8 are evaluated as important parameters for industrial applications. In addition, a possible mechanism based on experimental studies are proposed.
