中文摘要：
机动车尾气污染排放控制面临着贵金属资源短缺和价格飙升的问题，纳米催化科学的发展为解决这个问题提供了科学和技术上的基础。本课题以提高三效催化剂活性和降低贵金属含量为目的，采用超声辅助膜还原法制备了贵金属纳米粒子、贵金属纳米催化剂以及双金属三效催化剂，对金属纳米粒子成核与生长机制以及控制贵金属纳米催化剂（负载型Pt、Rh和Pd金属催化剂）载体上金属粒子（金属簇）的粒度、形状（结构）、化学组成的方法进行研究。同时还对贵金属纳米催化剂的三效催化模型反应（CO催化氧化、HC催化氧化和NOx催化还原）活性、选择性、反应路径以及催化剂的（水）热稳定性进行了考察。研究结果表明，利用"纳米效应"和"双金属催化剂（合金或核壳）结构制备技术"可以提高三效催化性能，有效降低三效催化剂的贵金属含量，从而制备出高活性低贵金属含量的纳米三效催化剂。此外，为了在分子水平上探究各个因素对催化剂活性的影响，搭建了2D催化反应体系，利用in-situ AFM为表征手段，对2D催化体系进行研究，必将为纳米催化科学的发展提供有用的实验数据。
