CO是性能优良的还原剂,如能不添加还原剂实现 CO催化还原 NOx,将成为最具经济技术优势的 NOx脱除技术。在富氧、低温条件下,利用 CO选择性催化还原 NOx为 N2,是目前选择性催化还原研究中的热点和难点。催化 CO还原 NOx常用的贵金属 Ir, Rh, Pt和Pd矿藏稀少,价格昂贵,有氧条件下活性急降,而分子筛催化剂和一些金属氧化物催化剂普遍存在反应温度高,尤其对 N2选择性差等问题。为解决上述问题,需寻找新的适合我国矿产资源的催化体系。研究发现,稀散金属基催化剂对氮氧化物的净化具有一定效果,因而可将我国的稀散金属资源优势转化为技术优势和经济优势。因此,本文以 TiO2-γ-Al2O3(TA)为载体, In/Ag为活性组分,采用等体积浸渍法制备了 InAg/TA以及 In/TA, Ag/TA和InAg/Al (γ-Al2O3为载体)催化剂,考察了贫燃条件下 CO选择性还原NO的催化活性。研究表明,双金属催化剂InAg/Al和 InAg/TA的活性比单金属催化剂In/TA和 Ag/TA高, In/TA催化剂中引入 Ag物种能降低起燃温度；另外,相比于InAg/Al催化剂, InAg/TA催化剂具有较高的催化活性,550?600°C时 N2产率超过60%,说明载体中引入TiO2可以提高催化剂活性。为了深入研究 InAg/TA催化剂中 Ag物种和TiO2对 In物种的作用,通过比表面测定、X射线衍射(XRD)、透射电子显微镜(TEM)、X射线光电子能谱、紫外-可见光吸收光谱、氢气程序升温还原、傅立叶变换红外线光谱等方法分析了催化剂结构和表面形态。结果表明, Ag物种可以提高 In物种的分散性, In和 Ag物种在 TA载体表面可以很好地分散,从而有利于提高催化活性。 In和 Ag物种在 TA载体表面以氧化态形式存在,并且 Ag物种可以提高 In物种表面含量,表面 In和 Ag物种含量越高,吸附活性位越多,催化活性越高；同时, TiO2也可以促进 NO吸附,从而提高 InAg/TA催化剂活性。 InAg/TA催化剂在450°C连续反应72 h进行稳定性测试,测试前后分别在50?600°C进行活性测试,并用 XRD和 TEM对反应后的催化剂进行表征测试。结果表明, InAg/TA催化剂具有较好的稳定性,连续反应前后催化剂活性基本保持不变,推测可能由于在有 CO和O2存在的体系中, Ag物种利用自身 Ag+与 Ag0之间的氧化还原反应抑制了活性组分 In2O3的还原和聚集,稳定了 In物种乃至催化剂活性。 InAg/TA催化剂用于贫燃条件下CO还原NO具有较好的催化效果,主要归因于催化剂活性组分分散性好,稳定性高,对NO吸附能力强。 Ag物种可以稳定In物种并提高其分散性, TiO2可以改善In物种和Ag物种的分散性并促进NO吸附。","authors":[{"authorName":"<span style=\"color:red\">吴</span><span
