摘要
光催化技术是一种治理环境污染的新技术,但由于光催化活性需要紫外光激发及量子转换效率低而制约了其推广应用。因此,开展该方面的理论研究,这对推动光催化技术的发展起到了重要作用。总结了不同离子掺杂及共掺杂对TiO_2晶体结构和光催化性能的影响规律,指导我们如何选择合适的掺杂离子以便有效地提高TiO_2光催化性能的方法。
Photocatalytic technology is a new method for environmental pollution control,but its application has been limited for low quantum conversion efficiency and for requiring of UV-light to excite photocatalytic activity.Therefore, the theoretical study in recent years has attracted attentions and promoted the development of photocatalytic technology. The influences of different ions doping or co-doping on TiO2 crystal structure and photocatalytic properties are summarized. Methods on how to choose appropriate doping ions have been suggested for effectively improving TiO2 photocatalytic property.
