摘要
卤氧化铋基半导体材料具有铋氧层和卤素层交替排布的独特层状结构和易调节的禁带宽度,在直接利用太阳光去除环境污染物方面表现出优异性能和巨大潜力.基于国内外相关研究进展及本课题组近年来的研究成果,该文综述了卤氧化铋材料(氯氧化铋、溴氧化铋和碘氧化铋)光催化去除环境污染物方面的研究成果,主要包括卤氧化铋光催化材料的设计和改性策略,以及上述新材料在重金属离子去除、有机污染物降解和空气净化等领域的研究进展.最后,提出了卤氧化铋光催化材料在环境污染控制领域的研究展望.
Bismuth oxide-based semiconductor materials possess a unique layered structure with alternate[Bi_(2)O_(2)]^(2+)and[Cl_(2)]layers,and an adjustable band gap,showing superior performance and great potential in the solar-light-driven environmental pollutants removal.On account of the relevant research progress of others and our latest research results,the research results on the photocatalytic removal of environmental pollutants with bismuth oxyhalide(bismuth oxychloride,bismuth oxybromide and bismuth oxyiodine)are summarized,mainly including the fabrication and modification strategies of bismuth oxyhalide photocatalytic,and the application of these new materials in the fields of heavy metal ion removal,organic pollutant degradation and air purification.Finally,the prospect of the research of bismuth oxyhalide photocatalytic material in the field of environmental pollution control are proposed.
