摘要:
高效光催化分解挥发性有机化合物的关键在于提高催化剂光生载流子的分离效率。采用TaON修饰BiO1.2I0.6,获得了一种新型宽光谱吸收富氧缺碘材料5%TaON/BiO1.2I0.6。研究发现,5%TaON/BiO1.2I0.6显示出优异的光催化分解典型VOCs甲苯的活性。经过300 W氙灯24 h照射,0.2 g 5%TaON/BiO1.2I0.6可以将约74%的甲苯降解,其降解效率为BiO1.2I0.6的1.4倍。5%TaON/BiO1.2I0.6中光生载流子的分离效率显著高于BiO1.2I0.6,这极大地增强了它的光催化活性。
Abstract:
The key to efficient photocatalytic decomposition of volatile organic compounds is to improve carrier separation-efficiency of the photocatalyst.In this work, TaON was used to modify BiO1.2I0.6, thereby obtaining 5%TaON/BiO1.2I0.6 composites with wide spectrum absorption and oxygen enrichment and iodine deficiency. The 5%TaON/BiO1.2I0.6 exhibited the optimal photocatalytic activity. About 74% of toluene was degraded over 0.2 g of 5%TaON/BiO1.2I0.6 after 24 h of irradiation using a 300 W xenon lamp, which was 1.4 times that over BiO1.2I0.6. Compared to BiO1.2I0.6,the distinctly enhanced photocatalytic activity of 5%TaON/BiO1.2I0.6 was basically attributed to efficient separation of photo-generated carriers.
