摘要
挥发性有机物(volatile organic compound,VOCs)被认为是主要的空气污染物,在空气中的含量被严格规定,如果超标,将会对人体健康造成危害,研究有效地去除VOCs的技术势在必行。TiO_2纳米复合光催化剂光催化氧化技术由于其强的光催化活性成为有效去除VOCs的技术之一。研究有效地降低TiO_2纳米光催化剂带隙能的策略,使其光活性由紫外向可见和红外偏移。通过调控孔道结构、设计复合光催化材料表面组分,从而改善其光催化活性,使其有效地光催化降解VOCs。
Volatile organic compounds (VOCs) are considered major air pollutants, and the amount of them in the air is strictly regulated. If they exceed the limit, they will do harm to human health. It is necessary to remove VOCs effectively. Photocatalytic oxidation has become one of the effective VOCs removal techniques due to its strong oxidation capacity. However, it makes photoactivity shift from the ultraviolet to the visible and the infrared by reducing the band gap energy. By adjusting the pore structure and designing the surface composition of the photocatalytic materials, the photocatalytic activity can be improved, leading to its effective photocatalytic degradation of VOCs.
