SO〓〓/M〓O〓 solid superacid was applied to the photocatalytic oxidation of organic pollutants for the first time. Porous SO〓〓/TiO〓 solid superacid catalysts with high specific surface area were prepared by sol-gel method. The photocatalytic degradation of bromomethane was used as model reaction. The influence of impregnation with H〓SO〓 solution on the structure of catalysts and their photocatalytic performance was systematically studied by using X-ray diffraction, X-ray photoelectron spectroscopy, N〓 sorption analysis applying BET method, UV-Vis diffuse reflectance spectroscopy, FTIR spectroscopy, O〓-TPD and photocatalytic activity measurement. The acidity of TiO〓-based catalysts was investigated by Hammett indicator method, NH〓-TPD and IR spectra of pyridine adsorbtion. The mechanism of superacidifing effects on photocatalytic performances such as the photocatalytic degradation rate of bromomethane, apparent kinetic constant and apparent quantum efficiency was discussed.The results indicated that SO〓〓 is combined with metal ions of TiO〓 in a chelating bidentate mode.

本文首次将SO〓〓/MxOy型固体超强酸催化剂用于光催化氧化有机污染物研究，采用溶胶-凝胶法制备了具有多孔性和大比表面结构的二氧化钛基固体超强酸光催化剂SO〓〓/TiO〓，以光催化降解溴代甲烷为模型反应，系统地研究了H〓SO〓浸渍处理对催化剂表面酸性及其气相光催化性能的影响，结合XRD、BET、XPS、FTIR、Hammett指示剂法、吡啶吸附红外光谱、NH〓-TPD、O〓-TPD、紫外可见漫反射光谱等多种表征手段，深入地讨论了超强酸化对TiO〓的改性机理，阐明了引起SO〓〓/TiO〓超强酸催化剂光催化降解溴代甲烷的转化率、表观反应速率常数和表观量子效率变化的本质原因。

Jq Ez6_{0An outbreak of highly pathogenic avian influenza caused by H5N1 virus occurred in Vietnam, Japan and Korea, commencing in December, 2003. By February, 2004, it has been distributed widely in Asia and brought heavy losses. H5N1 are ball-like RNA viruses, birds can shed them via respiratory system, ocular secretions and feces, sometimes transferred to human and cause lethal infection. H5N1 patients have prominent features of reactive hemophagocytic syndrome,bronchiolar inflammation, necrosis of bronchial epithelium and organizing,diffuse alveolar damage with interstitial fibrosis.

2003年12月，H5N1型禽流感病毒在越南、日本和韩国爆发，到2004年2月，该病毒已在亚洲广泛蔓延并带来了巨大损失。H5N1是球型RNA病毒，禽类间可通过呼吸系统、眼分泌物和粪便传播，也可传染人类甚至导致死亡。H5N1感染者的特征是反应性噬血细胞综合征、细支气管炎症、支气管上皮坏死和机化、弥漫性肺泡病变和间质纤维化。
