摘要: 因其显著威胁人体健康,挥发性有机物已成为影响室内空气质量的关键因素,亟需有效处理。本文回顾了目前净化室内挥发性有机物的主要技术,包括绿色植物法、吸附法、低温等离子体技术、金属催化氧化法、光催化氧化法等的研究成果,对各种净化技术的原理、影响因素进行了总结,并对其优缺点及未来需要解决的问题进行了分析。指出绿色植物法仅适于处理低浓度污染,一般作为辅助手段;吸附法的核心在于吸附剂,需考虑吸附剂的更换和再生问题;低温等离子体技术去除率较高,但成本也较高;金属催化氧化法需开发廉价且高效的金属氧化物催化剂;光催化氧化法的研究多集中于TiO2的改性,以期提高其光转化效率。本文同时简述了目前室内空气净化器市场的发展及各技术在市场应用中的占比情况,指出了各项净化技术在未来的热点研究领域。

Abstract: Volatile organic compounds(VOCs),which seriously threaten human health,have been the key factor influencing indoor air quality,and need to be treated effectively. In this paper,the main purification technologies of indoor VOCs were reviewed,including green plants,adsorption,non-thermal plasma(NTP),metal catalytic oxidation,and photocatalytic oxidation. The principles and influence factors of the purification technologies were summarized,and the merits and faults of each technology and problems need to be resolved in the future were analyzed. Green plants are just suitable for low concentration pollutants,and are usually used as supplementary means. The core of adsorption is the adsorbent,and the replacement of regeneration of adsorbent should be considered. For non-thermal plasma,the removal efficiency of VOCs by NTP technology is high,but the cost is high. As for metal catalytic oxidation method,the metal oxide catalysts with low price and high efficiency are needed to be developed. For photocatalytic oxidation technology,the current study is focused on the modification of TiO2 and improvement of light conversion efficiency. This paper also briefly presents the current situation of the air purifier market and the proportion of various technologies in the market. Then the technical research hot spots in the future were proposed.

Key words: indoor volatile organic compounds(VOCs), purification technologies, mechanism, catalyst
