在高效、广谱、环境友好的新型绿色洗消剂需求背景下,光催化技术逐渐脱颖而出,成为洗消技术研究的热点。特别是二氧化钛(TiO_2)光催化剂,已被用于降解包括化学毒剂在内的多类有机污染物。从20世纪90年代初至今,国内外针对TiO_2光催化消毒化学毒剂开展了大量研究工作,内容涉及材料制备与活性、消毒效果、反应机理与产物、催化剂失活与再生、应用研究等多个方面。该文对国内外相关研究成果进行了归纳和分析,并展望了今后开展的研究方向。
Under the background of the demand of new efficient, broad spectrum and environmentally friendly new green decontamination reagent, photocatalytic technology has gradually become a hot spot in the research of decontamination technology. In particular, titanium dioxide (TiO 2) photocatalysts have been used to degrade many types of organic pollutants, including chemical agents. Since the early 1990s, a great deal of researches have been carried out on the photocatalytic disinfection of TiO 2 at home and abroad, including material preparation and activity, disinfection effect, reaction mechanism and product, catalyst deactivation and regeneration, applied research and many other aspects . This paper summarizes the relevant research results at home and abroad, and looks forward to the future research direction.
