简要介绍了纳米光催化材料光解室内空气中VOC (挥发性有机化合物 )的原理及国内外在此领域的研究应用情况 ,特别是日本在空气净化器中的应用 ,认为近期应加强理论研究 ,除开发家用空气净化器外 ,还应重视该技术在集中空调领域中的应用。 The principle of photolysis of VOC (volatile organic compounds) in indoor air by nanometer photocatalytic material and the research application in this area at home and abroad are introduced briefly, especially the application of Japan in air purifier. It is suggested that theoretical research should be strengthened in the near future, In addition to the development of home air purifier, but also attach importance to the technology in the field of central air conditioning applications.
