Fabrication of Ordered Meso-macroporous HPW/TiO_2 Catalyst for Efficient Heterogeneous Oxidative Desulfurization

In order to reduce the emission of SO_x in the environment,sulfur compounds must be removed efficiently from fuels.Three-dimensional highly ordered meso-macroporous HPW/TiO₂ (3DO m/M HPW/TiO₂) materials were synthesized successfully by sol-gel method and applied as oxidative desulfurization catalyst for the model fuel.The characterization results displayed the existence of highly ordered meso-macroporous structures and the Keggin type of HPW was highly dispersed i...     

介孔-大孔HPW/TiO2催化剂的制备及其催化氧化脱硫性能的研究

为了有效降低SO_x在环境中的排放,以嵌段共聚物F127和新合成的PMMA微球为双模板,采用溶胶-凝胶法制备了三维有序介孔-大孔x-HPW/TiO₂催化剂。利用扫描电镜、透射电镜、氮气吸附-脱附、X射线衍射和红外光谱研究了其结构,并考察了其催化氧化燃油中有机硫的性能。结果表明,x-HPW/TiO₂催化剂中存在高度有序的介孔-大孔结构,Keggin结构的HPW均匀分散在TiO₂孔道骨架中。该催化剂在常压、60℃下可使燃油中的二苯并噻吩（DBT）催化氧化完全,循环使用6次后对DBT的去除率仍可达到96%。
