| 摘 要： | 总结近年来在TiO2与活性碳纤维复合光催化剂的合成方法、结构与性能,及对室内挥发性有机物光催化降解方面的研究,分析TiO2/ACF复合光催化剂对有机物吸附、富集、光催化、原位再生的过程,探讨活性碳纤维吸附材料对提高TiO2光催化剂量子产率的作用机制,认为低浓度污染物在催化剂表面的吸脱附速率提高是TiO2/ACF复合光催化剂具有较高降解能力的关健因素.

| Abstract: | The preparation, structure, properties and photocatalysis to volatile organic compounds of TiO2/ACF photocatalyst were reviewed. The effect of concentration, adsorption, photocatalysis and restoring of TiO2/ACF catalyst were analyzed, and mechanism of synthetical effect of activated carbon fibers and titanium dioxide were summarized. The adsorption and desorbtion of organic pollutants on TiO2/ACF photocatalyst were more efficient than pure TiO2 photocatalyst, which contributed to the high active TiO2/ACF photocatalyst. |
