摘　　要：随着化工、能源、环境等行业的发展,纳米催化剂受到越来越多的关注。尤其纳米TiO_(2)因具有优异的环境相容性、稳定的理化性质而被广泛应用于各行业,成为目前最具前景的“绿色”催化剂。该催化剂有颗粒状、棒状、片状、球状等多种形貌,其暴露晶面、活性位点数量受形貌的影响,继而影响其催化效率。综述不同形貌TiO_(2)的合成方法及影响因素,总结其在催化降解有机污染物及脱除烟气中NO_(x)的应用,发现中空结构的TiO_(2)纳米管无论是作为活性中心还是为载体,在去除环境污染物的过程中都表现出较好的催化性能,最后展望了未来纳米TiO_(2)在脱除挥发性含硫有机污染物中的应用及其形貌影响催化性能的机理研究。With the development of chemical,energy and environment industries,more and more attention has been paid to nano-catalysts.Especially,nano-TiO_(2)is widely used in various industries due to its excellent environmental compatibility and stable physicochemical property,and has become the most promising“green”catalyst at present.The catalyst has the morphology of zero dimension,one dimension,two dimension,three dimension and so on.The morphology of the catalyst will affect the number of exposed crystal faces and the number of active centers,thereby affecting its catalytic efficiency.The synthesis and influence factors of different morphology of TiO_(2) were reviewed,and summarized its applications in the catalytic degradation of organic pollutants and removing the NO_(x)in flue gas.It was found that the hollow structure of TiO_(2) nanotubes as active center and as the carrier,in the process of removing environmental pollutants showed better catalytic performance.Finally,the future study on the mechanism of the effect of nano TiO_(2) morphology on the catalytic performance and its application in the removal of volatile organic pollutants containing sulfur were prospected.
