摘要
随着我国工业化进程的加快,工业废水的排放也逐步受到重视。其中,高盐染料废水因其内部成分复杂、存在脱色困难、废水处理难度较大等问题,在工业废水中占有较大比重。TiO 2作为一种环境友好型的光催化剂,在污染治理方面有着广泛的前景。本文主要从光催化TiO 2纳米材料的机理、制备、改性和应用等方面进行阐述;综合分析了光催化材料研究领域仍存在的问题;展望了光催化材料的未来发展趋势。
With the acceleration of our country s industrialization process,the discharge of industrial wastewater has gradually received attention.Among them,high-salt dye wastewater occupies a large proportion of industrial wastewater due to its complex internal components,difficulty in decolorization,and difficulty in wastewater treatment.As an environmentally friendly photocatalyst,TiO 2 has broad prospects in pollution control.The mechanism,preparation,modification and application of photocatalytic TiO 2 nanomaterials were mainly discussed.The remaining problems in the research field of photocatalytic materials were comprehensively analyzed,and the future development trend of photocatalytic materials was prospected.
