Good evening, my fellow Americans: Tonight I want to speak to you of peace in Vietnam and Southeast Asia. No other question so preoccupies our people. No other dream so absorbs the 250 million human beings who liv e in that part of the world. No other goal motivates American policy in Southeast Asia. For years, representatives of our Governments and others have traveled the world seeking to find a basis for peace talks. Since last September they have carried the off er that I made public at San Antonio. And that offer was this:

采用凝胶溶胶法制备TiO2以及摩尔比分别为1:1和4:1的TiO2-ZrO2三种载体,然后浸渍负载一定量的活性组分MnOx制备相应催化剂.通过X射线衍射和扫描电镜对载体和催化剂进行表征,并进行氨气低温选择性催化还原NO(NH3-SCR)实验来考察催化剂的活性.三种载体中TiO2-ZrO2(4:1)的颗粒粒径最小且高度分散,加入氧化锆后,Zr4+离子取代Ti4+离子掺杂进入TiO2晶格内,引起TiO2晶格畸变,抑制TiO2晶型转变,并促进载体上活性组分Mn的均匀分布,从而提高催化剂的低温选择性催化还原活性.TiO2-ZrO2(4:1)加入质量分数10%的Mn后催化剂的活性最高,在130℃采用该催化剂催化时NO的转化率达到92.6%;150℃时通入体积分数10%的水蒸气会降低10%Mn/TiO2-ZrO2(4:1)催化剂的活性,撤消后活性可逐渐恢复;而200℃时10%Mn/TiO2-ZrO2(4:1)的活性基本不受水蒸气的影响
