Abstract

Abstract:

Indoor air quality has become an important health issue of public concern, and photocatalytic oxidation (PCO) technology has the characteristics of low energy consumption and high efficiency, which makes it show a greater potential in the treatment of indoor volatile organic compounds (VOCs). Among many PCO materials, titanium dioxide (TiO₂) has become the preferred catalyst for the degradation of indoor VOCs due to its wide source, stable chemical properties, strong oxidation ability, low toxicity, etc. However, its low utilization of visible light limits its application in the field of photocatalysis. This paper reviewed the research progress on the characteristic of TiO₂ materials and their use in indoor VOCs management, detailed the reaction mechanism of TiO₂ visible light photocatalytic degradation of typical indoor VOCs, compiled and summarized the relevant research on the enhancement of adsorption and catalytic oxidation properties of TiO₂ in recent years, introduced the research progress of indoor single/multi-component VOCs degradation in recent years and made an outlook for the future purification of indoor VOCs pollution by TiO₂ materials under visible light in order to provide an opportunity for the future degradation of single/multi-component VOCs. The research progress of indoor single/multi-component VOCs degradation in recent years was analyzed, and the future prospect of TiO₂ materials for visible light purification of indoor VOCs pollution was presented, and the suggestions for the future research on degradation of single/multi-component VOCs and their mixtures were proposed.

Key words: visible light photocatalytic oxidation, catalyst, indoor air pollutants, titanium dioxide, volatile organic compounds (VOCs)

摘要：

室内空气质量已成为公众关注的重要健康问题，光催化氧化（PCO）技术具有能耗低且效率高的特点，使其在室内挥发性有机化合物（VOCs）治理中展现出较大的潜力。在众多PCO材料中，二氧化钛（TiO₂）因其来源广、化学性质稳定、氧化能力强、毒性低等特点成为降解室内VOCs的优选催化剂，但其对可见光的利用率较低等问题限制了其在光催化领域的应用。本文综述了TiO₂材料的特性及其在室内VOCs治理方面的研究进展，详述了TiO₂可见光光催化降解室内典型VOCs的反应机理，梳理归纳了近年来提升TiO₂吸附和催化氧化性能的相关研究，分析介绍了近几年室内单/多组分VOCs降解的研究进展，并对未来TiO₂材料可见光下净化室内VOCs污染做出展望，为未来降解单/多组分VOCs及其混合物的研究提出建议。
