The structural and photocatalytic properties of TiO〓 as well as surface acidity were greatly improved by sulfation. SO〓〓/TiO〓 solid superacid with Hammett constant Ho less than -12.14 was prepared by treating the TiO〓 with 1.0mol. L〓 sulfuric acid solution and then calcining at 450℃ for 3h. When compared to unmodified TiO〓, the SO〓〓/TiO〓 superacid catalyst exhibited higher anatase content, smaller crystal size, higher specific surface area, centralized pore size distribution, and the blue-shifted band edge of uv-vis adsorption spectra. Furthermore, the SO〓〓/TiO〓 superacid also showed excellent reaction activity and stability for CH〓Br photocatalytic decomposition even under the moist reaction conditions. The apparent quantum efficiency of SO〓〓/TiO〓 was 10 times of that of TiO〓 catalyst for the photocatalytic degradation of bromomethane. Therefore, the SO〓〓/TiO〓 superacid catalyst is promising for practical application in environmental remediation.It was found that both L and B acid sites exist on SO〓〓/TiO〓 photocatalyst while only L acid sites on TiO〓 photocatalyst. On the basis of experimental results, the synergistic model of superacidic centers was proposed for SO〓〓/TiO〓 photocatalyst to explain the photocatalytic behavior and the mechanism of superacidifing effects, assuming that the adjacent L and B acid sites induced by SO〓〓 comprise cooperatively the superacidic center on superacid photocatalyst. The group cooperation of the superacidic center could strengthen the surface acidity, increase surface acid sites and the adsorbtion of O〓, promote separation of photogenerated electron-hole pair, enhance the interfacial transfer of charges and reversibility of water adsorption. Consequently the excellent photocatalytic activity, reaction stability and resistibility to humidity of SO〓〓/TiO〓 superacid photocatalyst may attributed to the group cooperated effect of the superacidic center on the photocatalyst.
研究结果表明:SO〓〓与TiO〓表面的结合为螯合式双配位结构;TiO〓光催化剂表面经H〓SO〓浸渍处理后,提高了表面酸性,改善了催化剂结构和光催化性能,当H〓SO〓浸渍浓度为1.0mol.L〓、烧结温度为450℃时,可制得SO〓〓/TiO〓超强酸催化剂(H〓<-12.14),其结构和光催化活性得到明显改善,与TiO〓相比,SO〓〓/TiO〓光催化剂的锐钛矿含量高、晶粒小、BET比表面积大、孔径分布集中、光谱吸收边蓝移,具有优异的光催化氧化活性、稳定性及抗湿性能,光催化降解溴代甲烷的表观量子效率比TiO〓催化剂提高了一个数量级,是一种有实际应用前景的高效光催化剂;由此提出了SO〓〓/TiO〓超强酸催化剂表面集团协同作用的超强酸中心模型,认为在SO〓〓/TiO〓超强酸催化剂表面,由SO〓〓诱导的相邻L酸中心和B酸中心组成了集团协同作用的超强酸中心,其集团协同作用显著地增强了催化剂表面酸性、增大了表面酸量及O〓吸附量、促进了光生电子和空穴的分离及界面电荷转移,具有可逆吸附水的性能,是SO〓〓/TiO〓超强酸催化剂具有优异的光催化氧化活性、很好的活性稳定性及抗湿性能的重要原因。

The author found that the big piece-size muscovites of China are the normal muscovites; the small-size muscovites in the metamorphic rock area are mainly phengite. The Indian muscovites studied both big and small piece-size of muscovite, are normal muscovites. The surface activity of Indian muscovite substrate is higher than China ones. Acid is easy to erode paralleling to the direction of the muscovite substrate face. Although acid treating does not destroy the muscovite structure, the thermal stability of muscovite has be decreased.

The results showed that in the growth period of R. glutinosa, soil ferulic acid, vanillic acid, and vanillin contents had a persistent increase, while β-hydroxybenzoic acid content increased first but decreased then. The addition of ferulic acid (8 μg·ml-1), vanillic acid (08 μg·ml-1), vanillin (12 μg·ml-1), and β-hydroxybenzoic acid (30 μg·ml-1) in water culture had stronger inhibitory effects on R. glutinosa root length, root mass, fresh plant mass, and plant height. Treating with test phenolic acids except β-hydroxybenzoic acid increased leaf chlorophyll content significantly, compared with the control. After treated with test phenolic acids, plant SOD and POD activities decreased after an initial increase, and plant malondialdehyde content increased. In the treatment of ferulic acid, root SOD and POD activities were the lowest, and roots were rotted and dead.
