MnO_2催化剂的制备及其催化氧化挥发性有机污染物的研究进展

A review on manganese dioxide catalyst for catalytic oxidation of volatile organic compounds

挥发性有机污染物(VOCs)由于其危害大、来源广,因此受到人们的普遍关注.热催化氧化技术在催化降解挥发性有机污染物方面具有独特的优势,而催化剂二氧化锰(MnO_2)由于其在室温下相对于其他催化剂具有较高的处理效果以及易制备等优点而被广泛研究和使用.本文作者着重讲述了催化剂MnO_2的特点、制备工艺、降解挥发性有机污染物效率的影响因素及其负载方式等在国内外的研究现状.

Volatile organic compounds（VOCs） are a major component in air pollutants and pose great risks to both human health and environmental protection. Thermal catalytic oxidation has been proved to be a convenient innovative technology for its ability to degrade VOCs completely. As a catalyst,MnO2 has shown a lot of advantages such as higher removal efficiency of VOCs at room temperature over other catalysts and has been widely used in the process of thermal catalytic oxidation. This review was focused on the research in the characteristics,preparation technology,impact factors that affect the removal efficiency of VOCs and the loading materials of MnO2.
