中文摘要：

以两种表面活性剂Brij-35和P123作为介孔结构造孔剂,通过水热晶化法,制备多种活性组分V2O5、WO3、Cu O和Al2O3共负载的Zr O2-Ti O2（ZT）基介孔复合氧化物催化剂V2O5-WO3-Cu O-Al2O3/Zr O2-Ti O2（简称VWCu Al/ZT）。研究结果表明,活性组分均匀分散于介孔载体中,该复合催化材料针对NO的NH3-SCR催化反应中,相比于浸渍法制备的非介孔I-VWCu Al/ZT和商用催化剂V2O5-WO3/Ti O2（V-W/Ti）表现出优异的低温催化活性和稳定性,可以在较宽温度范围（200℃~500℃）内实现NO的高效催化还原。

英文摘要：

A novel mesoporous Zr O2-Ti O2（ZT） based multi-component composite oxide catalyst V2O5-WO3-Cu OAl2O3/Zr O2-Ti O2（VWCu Al/ZT） was successfully synthesized by one-pot hydrothermal method using both Brij-35 and P123 as composite template. The results indicated that the active species of V2O5, WO3, Cu O and Al2O3 could be homogeneously dispersed into mesoporous Zr O2-Ti O2 catalyst carrier. Compared with the reference samples of non-mesoporous I-VWCu Al/ZT and the traditional commercial catalyst V2O5-WO3/Ti O2（V-W/Ti）, the prepared VWCu Al/ZT showed a superior low-temperature catalytic activity and high stability over the reaction of NH3-SCR of NO, especially high catalytic efficacy for NO reduction within a wide temperature range of between 200℃ to 500℃.
