摘要
随着光催化技术不断发展成熟,空气品质和生活用水安全等问题倍受关注,二氧化钛作为新型光催化材料,其原有的性能已不能满足人们的需要,因此需要不断地突破改性。目前在二氧化钛改性方面以金属掺杂、非金属掺杂、共掺杂等技术为主,通过提高二氧化钛比表面积,抑制电子空穴的复合,促进电子空穴对的分离,达到增强二氧化钛光催化活性的目的。本文阐述了近年来二氧化钛的掺杂改性技术的发展现状,并对二氧化钛改性技术的发展趋势进行了展望。
With the development of photocatalytic technology,air quality and water safety have attracted much attention.As a new type of photocatalytic material,titanium dioxide's original performance can not meet people's needs,so it needs to break through the modification constantly.At present,metal doping,non-metal doping and codoping are the main technologies in the modification of titanium dioxide.The purpose of enhancing photocatalytic activity of titanium dioxide is to increase the specific surface area of titanium dioxide,inhibit the recombination of electron holes and promote the separation of electron hole pairs.In this paper,the development status of doping modification technology of titanium dioxide in recent years is described,and the development trend of doping modification technology of titanium dioxide is prospected.
