High-performance and long-term stability of mesoporous Cu-doped TiO2 microsphere for catalytic CO oxidation

A Hydrothermally Stable Single-Atom Catalyst of Pt Supported on High-Entropy Oxide/Al2O3: Structural Optimization and Enhanced Catalytic Activity

“…With the dramatic increase of transport vehicles over the past decades, environmental problems caused by exhaust emissions (CO, NO x , and hydrocarbons) have attracted worldwide attention. − The United States Environmental Protection Agency (EPA) considered harmful air pollutants, such as nitrogen oxides (NO x ) and carbon monoxide (CO), as standard air pollutants . Among of them, CO is an odorless, colorless, and tasteless toxic gas .…”

CeO2-Supported TiO2−Pt Nanorod Composites as Efficient Catalysts for CO Oxidation

“…TiO 2 , as a typical metal oxide, exhibits high oxygen storage capacity and redox properties as well as active catalytic performance by enhancing the migration rate of surface-active oxygen atoms and plays an important role in the catalysis field [ 18 , 19 , 20 ]. For example, Liou’s team [ 21 ] prepared Cu-doped TiO 2 microsphere for catalytic CO oxidation. They think that the highly dispersed doping metals can increase the exposure of copper and TiO 2 matrix, thus leading to the improvement of catalytic performance.…”

Enhanced effect of H<sub>2</sub> pretreatment on CuO<sub><italic>x</italic></sub>/CeO<sub>2</sub> catalyst for the CO plasma catalytic oxidation

“…一氧化碳(CO)不仅易与血红蛋白结合, 严重危害 人体健康, 还是地面臭氧的重要前驱体, 可以与氮氧 化物(NO x )和挥发性有机化合物(VOCs)发生光化学反 应产生臭氧 [1,2] . 化石燃料驱动的发动机所产生的尾气 是CO主要的人为排放源 [3,4] , 包括道路机动车辆、非 道路发动机和交通工具; 由于尾气处理装置中的催化 剂需要一定的温度(通常在300℃以上)才能发挥最大 效率, 因此在冷启动阶段, 燃料不完全燃烧往往会导致 CO的过度排放 [5] . 目前, 热催化氧化技术被广泛用于 去除CO污染物, 但面对汽车冷启动这样的低温工况, 催化剂难以起燃, 无法满足高效去除CO的要求 [6,7] .…”
