多孔硫、氮共掺杂TiO2的制备及连续流动可见光光催化活性OA北大核心CSCDCSTPCD
Preparation of Hierarchical Porous S and N Co-doped TiO2 and Its Continuous-flow Visible Light Photocatalysis
以聚合物凝胶为模板,硫酸氧钛为钛源,合成了多孔硫、氮共掺杂TiO2可见光光催化剂.利用XRD、FE-SEM、TEM、UV-vis和XPS等方法对样品的结构、形貌、可见光吸收及掺杂元素的化学形态进行了表征.结果表明掺杂TiO2为锐钛矿相结构,其网状骨架是由介孔和大孔组成,组成大孔的壁厚在100～300 nm之间,大孔的孔径约为300 nm,有少量的Ti-S、Ti-O-S、O-Ti-N键存在于样品中.连续降解废水中亚甲基蓝溶液结果表明:该方法合成的多…查看全部>>
Hierarchical porous S and N co-doped TiO2 was synthesized using simple polymer gel template and titanyl sulfate as titanium source and characterized by XRD, FE-SEM, TEM, UV-vis and XPS methods. The result of XRD showed that TiO2 was in the anatase phase. FE-SEM showed a network-like structure containing meso/macropores. The macropores had diameter of ca. 300 nm and a wall thickness of 100-300 nm. XPS results revealed that Ti-S,Ti-O-S and O-Ti-N bonds have fo…查看全部>>
