摘要
现代建筑材料、装修材料、绝热材料、黏结树脂、地毯、气溶胶型清洁剂、空气清新剂等都会在室内产生许多化学物质(VOCs),其中有些物质对人体有致癌作用。随着人们对室内空气现状认识的增加,其对空气质量的要求也逐渐提高。为了迎合消费者改善室内空气质量的需求,目前市场上销售多款室内空气净化器产品。这些产品在降解室内VOCs时多采取的核心技术为等离子体或光催化技术,这两种方法在降解VOCs过程中会存在降解不完全的情况,同时伴随产生O3的问题,造成二次污染。因此,降解空气净化器尾端气体中的微量VOCs及O3是目前采用光催化或等离子体技术空气净化器开发完善的研究热点。
Modern building materials,decoration materials,thermal insulation materials,adhesive resins,carpets,aerosolbased cleaners,air fresheners,etc.all produce many indoor chemical substances(VOCs),some of which have carcinogenic effects on the human body.As people’s understanding of the status of indoor air increases,their requirements for air quality have gradually increased.In order to meet the needs of consumers to improve indoor air quality,a variety of indoor air purifier products are currently on the market.The core technology that these products often use when degrading indoor VOCs is plasma or photocatalytic technology.These two methods will not be completely degraded during the process of degrading VOCs,and at the same time,the problem of generating O3 will cause secondary pollution.Therefore,the degradation of trace VOCs and O3 in the gas at the end of the air purifier is a research hotspot that is currently being developed using photocatalytic or plasma technology air purifiers.
