VOCs催化剂的研究进展

Research Progress of Catalysts for VOCs

挥发性有机物(VOCs)是影响我国大气环境质量的主要气态污染物,已经成为我国“十四五”期间空气污染物重点指标之一。催化氧化法是当前处理挥发性有机物的主流技术之一,其核心是催化剂。对此,本文主要针对目前已报道VOCs催化剂进行综述,介绍了各类催化剂对常见VOCs的催化研究现状,并对催化剂的催化性能、反应机理等方面进行了概括,分析了催化剂的制备方法、前体类型、水蒸气浓度等对催化活性的影响。

Volatile organic compounds (VOCs) are the main gaseous pollutants that affect the quality of China’s atmospheric environment, and have become one of the key indicators of air pollutants during the “14th Five-Year Plan” period in my country. Catalytic oxidation is one of the mainstream technologies for dealing with volatile organic compounds, and its core is a catalyst. In this regard, this paper mainly reviews the VOCs catalysts that have been reported so far, introduces the current research status of various catalysts on common VOCs, and makes an overview of the catalytic performance and reaction mechanism of the catalysts, the effect of precursor type, water vapor concentration, etc. on the catalytic activity.
