光催化处理挥发性有机物研究进展

Research progress in photocatalytic treatment of volatile organic compounds

简要阐述了挥发性有机物的定义、多种来源、对人体和环境的危害以及常用的处理技术,并对室内、室外主要挥发性有机物的种类及危害进行了分类整理,也对处理挥发性有机物的光催化技术在原理和方法上进行了总结;综述了光催化处理醛类和芳烃类的研究现状,并进行了简要分析;最后提出了光催化技术在降解机理上欠缺的问题,并对未来的研究方向进行了分析和展望。

The definition,various sources,harm to the human body and the environment,and the commonly used treatment technology of volatile organic compounds(VOCs） are described briefly.The types and harms of main VOCs in indoor and outdoor are classified and summed up.The principle and method of the photocatalytic technology that is used to treat with VOCs are summarized.The research situation for photocatalytic treatment of aldehyde and aromatic VOCs is reviewed and analyzed briefly. Based on analysis,the problem that the photocatalytic technology is short of degradation mechanism is proposed and the future research directions for photocatalytic technology are suggested and prospected.
