中文摘要:
      以乙酸锌为锌源,采用溶胶-凝胶法制备了金属泡沫镍网负载稀土元素镧掺杂氧化锌薄膜光催化剂。采用XRD、SEM、XPS、UV-vis对样品进行表征分析。并以废水中含量较大的抗生素磺胺二甲嘧啶为目标分解物,考察了薄膜催化剂在紫外灯下的光催化性能。结果表明:镧元素以三价正离子存在于薄膜中,镧成功掺入到氧化锌晶格中;镧掺杂降低了催化剂的禁带宽度,晶体颗粒变小,比表面积增大;薄膜催化剂表面分布均匀;镧掺杂氧化锌薄膜对抗生素有更高的催化效率。为光催化降解抗生素研究提供了新的思路。
Construction of La3+/ZnO on nickel foam and its photocatalytic performance
英文关键词:nickel foam  ZnO thin film  La doped  photocatalysis
英文摘要:
      The La3+/ZnO photocatalytic film catalyst was prepared by sol-gel method with zinc acetate as zinc source. The samples were characterized by XRD, SEM, XPS and UV-vis. The photocatalytic properties of thin film catalyst under UV light were investigated with sulfamethazine as the target decomposition. The results showed that lanthanum as trivalent positive ions exists in the film, and lanthanum was successfully mixed into ZnO crystal lattice; lanthanum doping reduced the gap width of the catalyst, the crystal particles decreased, and the specific surface area increased; The surface of thin film catalyst was uniform; Lanthanum doped ZnO films had a higher catalytic efficiency for antibiotics. This work will bring about potential application in treatment of antibiotic pollutant
