本文综述了近年来环境催化剂材料的合成和表征的研究进展。用于分解挥发性有机化合物和氮氧化物的高度先进的环境催化剂是基于固态化学和固态离子学领域中通常使用的概念人为设计的。采用柠檬酸溶胶-凝胶法制备了催化乙烯完全氧化的活性材料，并将其作为获得CeO(2)-ZrO(2)-Bi(2)O(3)固溶体的关键工艺。另一方面，针对晶格中的开放空间和氧化阴离子空位，设计并制备了NO直接分解催化剂。评价结果表明，该材料作为环境催化剂具有明显的优越性。介绍了这些协奏曲催化剂的设计策略、合成方法和结构特点。
Recent advances in the synthesis and characterization of materials for environmental catalysts are reported in this paper. Highly advanced environmental catalysts for decomposition of volatile organic compounds and nitrogen oxides were artificially designed based on a concept usually employed in the fields of solid-state chemistry and solid-state ionics. Catalytically active materials for complete ethylene oxidation were prepared by a citrate sol-gel method as a key process to obtain CeO(2)-ZrO(2)-Bi(2)O(3) solid solutions. On the other hand, direct NO decomposition catalysts were designed and prepared focusing on the open spaces and oxide anion vacancies in the crystal lattice. Evaluation of the materials as environmental catalysts demonstrated significant advantages over the conventional ones. The design strategy, synthetic method, and structural features of these concerto catalysts are addressed.
