Abstract:

Transition metal monosubstituted Keggin-type tungstophosphates(PW11M, M=Ti4+, Cr3+, Mn2+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+) were synthesized and supported in a Cu3(BTC)2 metal-organic framework, a series of transition metal-substituted polyoxometalate-based metal-organic framework hybrids[PW11M@Cu3(BTC)2] was obtained. The compositions, structures and porosity of the hybrids were determined by single crystal X-ray diffraction analysis, elemental analysis(ICP), powder X-ray diffraction(PXRD), thermogravimetric analysis(TG), N2 adsorption-desorption experiment, etc. The series of hybrid materials have good adsorption effect on dibenzothiophene in fuel oil, and rapidly catalyze its oxidation to dibenzothiophene sulfone, and realize deep desulfurization of fuel oil with oxygen as oxidant.

Key words: Transition metal, Monosubstituted Keggin-type polyoxometalate, Metal-organic framework, Oxidative desulfurization
