  • 摘要: 以煅烧后的珍珠贝壳为载体,采用原位水解法制备出纳米Cu2O/珍珠贝壳复合光催化材料.通过活性大红染料B-3G的脱色实验对光催化材料的活性进行讨论,并采用XRD、SEM、EDS、FT-IR和UV-Vis对材料进行表征.结果表明,以1050 ℃煅烧的珍珠贝壳为载体制备的纳米Cu2O/珍珠贝壳复合材料的光催化活性最强.Cu2O颗粒产率高且呈椭球状,平均粒径为20 nm;水解负载过程中,Cu2O颗粒与珍珠贝壳载体间形成了新的化学键.纳米Cu2O/珍珠贝壳复合材料对紫外光及可见光均有良好的吸收.
    Abstract: Nano-Cu2O/pearl shell composite photocatalysts were prepared through in-situ hydrolysis process with calcined pearl shells as carriers. Photocatalytic activities of these products were investigated by the decolorization of Reactive Red dye B-3G in solutions. These catalysts were characterized by XRD, SEM, EDS, FT-IR and UV-Vis. The experimental results show that the photocatalyst prepared with pearl shells calcined at 1050 ℃ has the highest photocatalytic activity. Loaded Cu2O particles, with an average diameter of 20 nm, are oval in shape. New chemical bonds have formed between Cu2O particles and pearl shell carriers during the in-situ hydrolysis process. Nano-Cu2O /pearl shell composite photocatalyst has good response to both ultraviolet and visible light.
