摘要:
 稀土氧化物,尤其是镧、铈等轻稀土元素的氧化物,被广泛应用于催化领域。本文围绕以CeO2为代表的稀土催化材料在大气污染治理中的作用进行了综述,详细介绍了铈基稀土催化材料在机动车尾气净化、烟气脱硝、挥发性有机污染物催化燃烧等领域的最新研究进展。在汽油车尾气净化方面,如何进一步提高CeO2基复合氧化物自身的稳定性,同时提高活性金属的利用效率、延长催化剂使用寿命是研究重点;在柴油车氮氧化物和颗粒物的排放控制方面,通过成分调控,利用稀土氧化物特别是氧化铈提高催化剂的低温活性、抗中毒性能和水热稳定性等是研究热点;在固定源烟气脱硝方面,稀土氧化物尤其是氧化铈基脱硝催化剂具有高效、无毒、无二次污染性等特点,可逐步替代高毒的钒钛系,实现环境友好;在挥发性有机物催化燃烧方面CeO2催化材料也已被实验证明具有良好的催化氧化能力。本综述旨在为促进本领域的研究者更清楚地了解铈基稀土催化材料在大气污染治理中所发挥的作用及应用潜力,同时为科学地设计下一代高性能催化材料和应用提供参考。
Abstract:
Light rare-earth oxides such as La, Ce-containing oxides were widely applied in catalysis. The present review mainly sumarized the research progress of ceria-based catalytic materials in air pullotion purifaction, including automotive exhaust purification, industrial denitrification, and catalytic combustion of volatile organic compounds (VOCs). For automotive emission control, improving the stablity of CeO2-based cataysts as well as the utilization of the precious metals was critical for prolonging the lifetime of the catalysts. For NOx and soot elimination, using rare earth oxides, especially CeO2, to improve the low-temperature activity, anti-poisoning performance and hydrothermal stability of the catalysts was a research hotspot. For denitrification in stationary source, due to the characteristics of high efficiency, non-toxicity and no secondary pollution on CeO2-based cataysts, it had a potential for these catalysts to gradually replace those high toxic vanadium-titanium catalysts. For VOCs catalytic combustion, CeO2 materials had also been proved to own good catalytic oxidation ability. The purpose of this review was to help researchers in this field to understand the role and application potential of cerium-based rare earth catalytic materials in air pollution control. It also provided a reference for the further scientific design and application on high-performance catalysts.
