|
摘要
TiO_2凭借其优越的光催化性能,在环境治理方面得到了广泛应用。为了增加纯TiO_2的可见光利用率以及提高其量子效率,Ag修饰TiO_2得到了广泛的研究。根据光催化剂形貌分类,综述了近年来Ag修饰TiO_2微粒、薄膜、纳米管、纳米线的制备工艺以及光催化性能研究,并展望了Ag改性后的TiO_2应用前景。
TiO_2 is widely used in the field of pollutant treatment because of its high photocatalytic efficiency.In order to increase the visible light utilization rate and quantum efficiency,Ag modified TiO_2 has been widely used.According to the morphology,the preparation and application in photo catalytic oxidation of Ag modified TiO_2 powders,thin films,nanotubes and nanowires were reviewed.Ag modified TiO_2 research trends in the future were prospected.
