中文摘要: 排放到公路隧道中的汽车尾气是造成隧道空气污染的主要因素,采用有效方法除去隧道中的污染气体具有重要意义,纳米多孔材料和纳米催化科学的发展为解决这一问题提供了新的思路。在本项目中,我们提出以基于MOFs材料的催化剂和吸附剂来消除公路隧道中的汽车尾气污染物。即以MOFs材料作为载体,通过负载贵金属(Pt、Rh和Pd)纳米粒子和纳米氧化物,探索制备在常温下可将CO催化转化为CO2的催化剂;通过对MOFs材料进行改性,探索制备在常温下对NOx和HC具有吸附能力的吸附剂。

英文摘要: The vehicle exhaust is the main pollutant in highway tunnel,it has important significance to find effective ways to reduce them. The development of nanoporous materials and nanocatalysis science has provide a new mentality for us. In this project, we propose a resolution that the catalysts and adsorbents based on MOFs would be used to reduce the vehicle exhaust pollutants in highway tunnels. The MOFs will be used as surpports to load noble metal (Pt, Rh and Pd) nanoparticles and nanoscle metal oxide, to try to prepare the catalysts that can convert CO to CO2 at normal temperature; The adsorbents that can adsorb NOx and HC at normal temperature will be try to prepared by modify the MOFs.
