The Synthesis of Poly Acid Based Nanocrystals and Their Application in Catalytic Oxidation Desulfurization
This study aims to explore the application of polyoxometalates(POMs)in catalysis and their dispersion strategies in metal organic frameworks(MOFs).Polyanions have attracted much attention due to their unique acidity and redox properties,but their poor dispersibility in non-polar solvents limits their catalytic performance.This study prepared a composite of Keggin type polyacids and Zn(TPB)2(1,3,5-tribenzoic acid)framework using hydrothermal synthesis method,achieving efficient dispersion of polyacids in MOFs.The research results indicate that the synthesized multi-acid based porous material exhibits excellent catalytic activity in the preparation of dimethyl ether by methanol dehydration and oxidative desulfurization reactions.In addition,by controlling the synthesis conditions,the control of crystal particle size has been successfully achieved,providing a new strategy for the design of multi acid catalysts.
