摘要
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。
Large efforts have been made to find high efficient, broad-spectrum and environmental benign novel decontaminant. Since 1990 s, titanium dioxide（TiO_2） has attracted a considerable attention due to its reactivity toward a large number of organic compounds, including chemical warfare agents CWAs. A variety of studies on TiO_2 in the field of CWAs decontamination, involving preparation and catalytic activity, deactivation and regeneration, reaction products and mechanism,decomposition effect and application research, have also been carried out to meet the requirements. In this paper, the recent progress of TiO_2 in the decontamination field was summarized and analyzed. The possible future research directions of CWAs decontamination by TiO_2 photocatalyst were prospected as well.
