赤泥作为氧化铝生产过程中产生的固体废弃物，会对生态环境造成严重污染，并对人类健康造成危害。因此，这类固体废物的资源化是可持续发展的有效途径。综述了近年来赤泥基催化剂在NH3催化还原氮氧化物（NOx）、催化氧化CO和挥发性有机物（VOCs）等典型大气污染物方面的研究进展。讨论了影响催化剂性能的因素及结构与活性的关系。展望了该类催化剂的发展前景和方向。该研究有助于赤泥的高附加值利用，减轻大气污染。
Red mud, as a solid waste produced during the alumina production, can cause severe eco-environmental pollution and health risks to human. Therefore, the resourcing of this type of solid waste is an effective way for the sustainable development. This paper reviews the recent progress on red mud-based catalysts for the removal of typical air pollutants, such as the catalytic reduction of nitrogen oxides (NOx) by NH3(NH3-SCR) and the catalytic oxidation of CO and volatile organic compounds (VOCs). The factors influencing the catalytic performance and the structure–activity relationship have been discussed. Future prospects and directions for the development of such catalysts are also proposed. This review would benefit for the high value-added utilizations of red mud in mitigating atmospheric pollutions.
