摘要:

光催化处理可挥发性有机物(VOCs)技术发展迅速,影响该过程的可操作因素较多,本文系统总结了影响光催化降解VOCs的因素和研究方法,围绕光催化反应过程和动力学规律分析,阐明了光传递、目标物的浓度和气速、系统湿度、反应器等因素对光催化降解的作用机理,揭示了光催化反应过程存在的问题和今后的研究方向。

Abstract:

The operable factors, including concentration/gas velocity of target, light transmission, relative humidity and reactor types of the heterogeneous photocatalytic degradation of VOCs, were discussed in this paper. The photocatalysis and photocatalytic degradation kinetics/mechanisms were described, and its limitation in both photon transfer and mass transfer were included. The important issues in future design and research was prospected.
