摘　　要：TiO_(2)具有催化性能好、物理化学性质稳定和无毒等特点,在TiO_(2)载体负载活性组分的基础上,介绍了其作为脱硝催化剂载体的优势。综述了TiO_(2)载体的成型及其在脱硝行业的应用状况。TiO_(2)载体在脱硝行业的应用主要有两种:一是纯TiO_(2)载体脱硝催化剂;二是TiO_(2)载体负载钒、钨、稀土铈等。今后的发展方向将会以提高TiO_(2)载体的使用寿命、防止TiO_(2)载体中毒和负载活性更高的组分为主,以此提高脱硝催化剂的使用寿命和脱硝率,以满足烟气和移动源尾气超低排放等日益严苛的环保要求。TiO_(2)carrier has good catalytic performance,stable physical and chemical properties and non-toxic characteristics.The advantages of titanium dioxide as denitration catalyst carrier are introduced on the basis of catalyst carrier loading active components.The forming of titanium dioxide carrier and application of titanium dioxide carrier in denitration industry were reviewed.Pure titanium dioxide and titanium dioxide carrier loaded with vanadium,tungsten,rare earth cerium,etc.as denitration catalysts are two main applications of TiO_(2).The future development direction will focus on improving the service life of titanium dioxide carrier,preventing titanium dioxide carrier poisoning and adding more active components,and improving the service life of denitration catalyst and denitration efficiency to meet the increasingly stringent environmental requirements of ultra-low emissions of flue gas and mobile source tail gas.
