摘要:

采用水热法在温和条件下制备了V掺杂的TiO2/活性炭(AC)光催化剂.利用XRD、SEM、漫反射、红外及荧光光谱对催化剂的物化性质进行了表征.结果显示,V-TiO2仍保持了锐钛矿相,没有出现V的衍射峰.相比纯TiO2,经过V掺杂的样品,具有较高的表面羟基密度,较低的栽流子复合几率,同时吸收光谱向可见光区移动.将纳米级的V-TiO2沉积在AC上可形成微-纳结构.在可见光照射下,V-TiO2/AC催化降解4-氯苯酚的能力高于纯V-TiO2和P25,这可归因于V的掺杂和AC协同作用的结果.

Abstract:

V-doped TiO2/activated carbon(AC) photocatalysts were prepared by hydrothermal method under mild conditions. XRD, SEM, diffuse reflectance, infrared and fluorescence spectroscopy were used to characterize the physical and chemical properties of the catalyst. The results show that V-TiO2 still maintains the anatase phase without the diffraction peak of V. Compared with pure TiO2, V-doped samples have higher surface hydroxyl density, lower planter recombination probability, and the absorption spectrum shifts to the visible region. Nanoscale V-TiO2 can be deposited on AC to form micro-nano structures. Under visible light irradiation, V-TiO2/AC catalytically degraded 4-chlorophenol was higher than pure V-TiO2 and P25, which could be attributed to the doping of V and the synergistic effect of AC.
