摘　　要：合成了过渡金属单取代的Keggin型钨磷酸盐(PW_(11)M,M=Ti^(4+),Cr^(3+),Mn^(2+),Fe^(3+),Co^(2+),Ni^(2+),Cu^(2+)和Zn^(2+)),并将其担载在Cu_(3)(BTC)_(2)金属有机框架中,合成了一系列过渡金属取代的多酸基金属有机框架杂化物[PW_(11)M@Cu_(3)(BTC)_(2)].通过单晶X射线衍射分析、元素分析(ICP)、粉末X射线衍射(PXRD)、热重分析(TG)和氮气吸附-脱附实验等确定了杂化物的组成、结构和多孔性.该类杂化材料对燃料油中二苯并噻吩具有良好的吸附作用,并催化其快速氧化为二苯并噻吩砜,实现了以氧气为氧化剂的燃料油深度脱硫.Transition metal monosubstituted Keggin-type tungstophosphates(PW_(11)M,M=Ti^(4+),Cr^(3+),Mn^(2+),Fe^(3+),Co^(2+),Ni^(2+),Cu^(2+),Zn^(2+))were synthesized and supported in a Cu_(3)(BTC)_(2) metal-organic framework,a series of transition metal-substituted polyoxometalate-based metal-organic framework hybrids[PW_(11)M@Cu_(3)(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),N_(2) adsorp⁃tion-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.
