摘　　要：首先通过简单沉淀法制备了薄片状纳米ZnO,再利用化学吸附作用将C60与ZnO复合得到C60/ZnO纳米复合材料。采用XRD、SEM、XPS、Ra-man、DRS、PL等技术对样品进行表征,紫外光下以亚甲基蓝(MB)作为探针分子,研究C60/ZnO纳米复合材料的光催化活性。结果表明,C60/ZnO纳米复合材料的光催化活性优于单纯的纳米ZnO,且1%(质量分数)C60/ZnO的光催化活性最高,这是由于C60具有良好的接受和传导电子的作用,抑制了光生电子和空穴的复合,从而提高了光催化效率。The flake-like nanostructured ZnO was firstly synthesized though a simple precipitation route, wHuw ing the C60/ZnO nanocomposites were fabricated via chemical adsorption method. The obtained samples were characterized by XRD, SEM, XPS, Raman, DRS and PL. The photocatalytic activities of as-prepared samples were evaluated under UV light irradiation using methylene blue （MB） as probe molecule. The experimental re- suits showed that the C60/ZnO nanocomposites exhibited the enhanced photocatalytic activity, which were high er than the pure ZnO. In addition, lwt% C60/ZnO nanocomposite had the best photocatalytic performance. The significantly enhanced photocatalytic activity for the present nanocomposite originated from the excellent elec- tron-accepting and electron-transport property of C60, which inhibited the recombination rate of photogenerated electron-hole pairs.
