稀土材料在挥发性有机废气降解中的应用及发展趋势

稀土材料由于富含表面羟基、表面晶格缺陷和具有高温稳定性，结合其强挥发性有机物（VOCs）亲和性以及优异储氧和释放能力等优势，在大气污染控制领域的应用十分广泛。近年来的研究发现，部分稀土基材料在VOCs处理上的效果优于贵金属催化剂，在实际工程中也显示出广泛的应用前景。在文献及工程调研的基础上，综述了稀土基材料在国内外催化领域、吸附领域以及实际工程应用中的现状，分析了稀土材料的优势以及目前面临的难题。从吸附、催化等角度分析了稀土材料在国内外的发展趋势，同时结合我国当前国情指出发展中的关键问题及解决方案，期望能为稀土材料在VOCs治理领域的更好发展提供参考。

APPLICATION AND DEVELOPMENT TREND OF RARE EARTH MATERIALS IN DEGRADATION OF VOLATILE ORGANIC WASTE GAS

Rare earth materials are widely used in the field of air pollution control due to their rich hydroxyl groups, surface lattice defects and high-temperature stability, combined with their strong VOCs affinity and excellent oxygen storage and release capabilities. Recent studies have found that some rare earth-based materials are better than noble metal catalysts in the treatment of organic waste gases, and have explored in a wide range of prospects in practical engineering applications. Based on the literature and engineering investigations, the current status of rare earth-based materials in the fields of catalysis, adsorption, and practical engineering at home and abroad is reviewed. The advantages of rare earth materials and the problems they are currently facing are analyzed. The development trends of rare earth materials at home and abroad are analyzed and predicted from the perspective of adsorption, catalysis, etc. At the same time, the key issues and solutions in development are pointed out in accordance with China's current national conditions, in order to provide references for the future development of rare earth materials in the field of organic waste gas treatment.
