【摘要】：催化燃烧是处理挥发性有机物(VOCs)的有效处理技术之一。催化燃烧的核心是制备高效稳定的催化剂,随着多孔材料制备技术的发展,具有三维有序大孔(3DOM)的钙钛矿催化剂表现出较好的催化燃烧稳定性和活性,受到人们普遍关注。本文结合近几年国内外3DOM钙钛矿催化剂的主要研究成果,在3DOM钙钛矿催化剂的结构、性能及制备方法等方面的研究成果概述的基础上,分析了其热稳定性、机械稳定性、疏水性、氧化还原性及酸碱性等功能化方面的最新进展,指出了目前3DOM钙钛矿催化剂亟待解决的问题,最后对今后的研究趋势进行了展望:胶体晶体模板的合成方法的改进、多功能性3DOM钙钛矿催化剂的制备及其对催化活性的影响机理的研究是今后发展的方向。
[Abstract]:Catalytic combustion is one of the effective treatment technologies for volatile organic compounds (VOCs). The core of catalytic combustion is the preparation of highly efficient and stable catalysts. With the development of porous material preparation technology, perovskite catalysts with three dimensional ordered macroporous (3Dom) have shown good catalytic combustion stability and activity, which has attracted widespread attention. Combined with the main research achievements of 3Dom perovskite catalyst at home and abroad in recent years, the thermal stability and mechanical stability of 3Dom perovskite catalyst were analyzed on the basis of summarizing the structure, performance and preparation method of 3Dom perovskite catalyst. The recent progress in hydrophobicity, redox, acid and alkalinity and so on is pointed out. The problems of 3Dom perovskite catalyst are pointed out. Finally, the research trend in the future is prospected: the improvement of the synthesis method of colloidal crystal template. The preparation of multifunctional 3 Dom perovskite catalyst and the mechanism of its influence on the catalytic activity are the development directions in the future.
