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。

In this research, B2 gene of HCV was highly expressed as a fusion protein (Trx-B2) by cloning into pThioHisA, and induced specific anti-HCV antibody in higher titer than unmodified B2 protein after immunize mice or rabbit.The results showed antigen Trx-B2 has obvious immunogenicity and induced specific antibody,which might be able to serve as diagnosis HCV. Consequently, this PcAb of rabbit was used to coated Immulon plate, and a method of both antibodys sandwiching antigens was developed to detect 32 HCV positive serum and 32 nomal serum.Results show that ratio of positive are 87.5%and 43.75% respectively.

Polyols can be divided into latex polyol and dispersion polyolaccording to the way of preparation. In this paper, acrylic latex polyol and acrylic dispersionpolyol were synthesized respectively. One kind waterborne polyisocyanate, which was waterbornehexamethylenediisocyanate trimer, was obtained by hydrophilic modification. Andisophorone diisocyanate trimer (T1890E), which can formulate into 2K-WPU coatings withpolyols, was selected from the unmodified polyisocyanates.
