中文摘要:

      一氧化碳（CO）的过度排放对地区空气质量和人体健康造成严重威胁。因此，CO 的治理迫在眉睫，目前CO催化氧化技术是治理CO的最有效的方法。针对CO催化氧化反应的催化剂可分为两类：贵金属催化剂和非贵金属催化剂。贵金属催化剂因其催化效率高、耐水抗硫性能好，在 CO 催化净化中受到了广泛的关注。然而，贵金属的稀缺性和昂贵价格以及复杂的烟气组分，限制了其在工业烟气治理领域的应用。非贵金属催化剂（如Mn、Cu、Co、Ce等等过渡金属氧化物）因其成本低廉，储量丰富，被研究人员视为贵金属催化剂的替代，也逐渐成为研究热点。此外，随着环保标准的日益严格，推动CO氧化催化剂的工业化应用也是当前阶段研究的重点和难点。本综述系统的总结了近年来对于CO氧化消除催化剂的研究和应用，重点讨论了催化剂活性组分、载体及等因素对催化剂活性、抗中毒性能的影响，并展望了CO氧化消除催化剂的研究和应用发展前景。

英文摘要:

      Excessive emissions of carbon monoxide (CO) severely threaten regional air quality and human health, rendering CO mitigation an urgent priority. CO catalytic oxidation technology stands as the most effective method for CO elimination. Catalysts for CO catalytic oxidation can be classified into two categories: noble metal-based catalysts and non-noble metal-based catalysts. Noble metal catalysts have attracted extensive attention in CO purification due to their high catalytic efficiency and excellent water/sulfur resistance. Nevertheless, their industrial application in flue gas treatment remains limited by the scarcity and high cost of noble metals, as well as the complexity of flue gas components. Non-noble metal catalysts, such as transition metal oxides (e.g., Mn, Cu, Co, Ce), are increasingly regarded as viable alternatives to noble metal catalysts owing to their low cost and abundant reserves, gradually becoming a research focus. Additionally, under increasingly stringent environmental regulations, advancing the industrial-scale application of CO oxidation catalysts has emerged as both a critical objective and a significant challenge in current research. This review systematically summarizes recent progress in CO oxidation catalysts, focusing on the effects of active components, supports, and other factors on catalytic activity and anti-poisoning performance. Prospects for future research directions and practical applications of CO oxidation catalysts are also discussed.
