摘要/Abstract

摘要： 采用溶胶–凝胶法制备了TiO₂和Bi掺杂的TiO₂纳米颗粒, 用N2吸附-脱附、SEM、XRD、FT-Raman、UV-Vis DRS对光催化材料的孔结构、表面构造、能带结构、吸光特性进行了表征, 并考查了其光催化甘油水溶液制氢反应的活性. 结果表明: Bi掺杂后的TiO₂为介孔结构的锐钛矿晶型纳米颗粒, 其分散度明显增加, 晶粒变小, 比表面积增大; Bi掺杂使得TiO₂禁带内形成杂质能级, 降低了禁带能量, 增加了光生电子和空穴的分离效率, 有利于将TiO2的吸光带边界扩展至可见光区; Bi掺杂的TiO₂样品表现出了远高于纯TiO₂的光催化甘油水溶液制氢性能, 2mol%Bi掺杂的样品在紫外光和模拟太阳光辐射下表现出了最高产氢活性, 其速率分别为3534.8 μmol/(h·gcat)和 455.7 μmol/(h·gcat).

Abstract: TiO₂ and Bi³⁺-doped TiO₂ semiconductors were prepared by using Sol-Gel method. Their pore size distribution, crystal structure, surface composition, photo absorption properties and photocatalytic performance for H₂ evolution from glycerol solution were investigated by techniques of N₂ adsorption-desorption, XRD, FT-Raman, SEM, UV-Vis DRS and photocatalytic reaction. The results show that Bi³⁺-doped TiO₂ appears anatase phase nanoparticles with mesoporous structure and has a much smaller crystallite size and much higher BET surface area than bare TiO₂. These samples exhibit a visible-light absorption capability much higher than bare TiO₂, which mainly originates from the doping process with the formation of new energy level of Bi³⁺ between conduction band and valence band of TiO₂ to reduce the energy gap and the electron–hole recombination rate. The Bi³⁺-doped TiO₂ samples display improved photocatalytic H₂ production from glycerol solution, and 2%Bi-doped TiO₂ shows a maximum H₂ production rate of 3534.8 μmol/(h·gcat) under UV irradiation and 455.7 μmol/(h·gcat) under simulated-solar irradiation, respectively.
