摘要: 本文以活性炭纤维(ACFs)为基底，采用溶胶–凝胶法–水热法合成了尺寸均一、高度定向、均匀生长的ZnO纳米棒阵列。通过SEM、XRD、N2物理吸附提出了ZnO纳米棒的生长机理，醋酸锌浓度对ZnO纳米棒的形貌起到调控作用，ZnO薄膜为纳米棒的定向生长提供了晶核，促进了其沿着活性炭纤维c轴方向择优生长。通过光催化性能测试表明醋酸锌浓度显著影响了ZnO纳米棒阵列/活性炭纤维复合材料的光催化性能，当醋酸锌浓度为0.15 mol∙L−1时，120 min内对亚甲基蓝的去除率高达90%，经五次再生循环后，其光催化效率仍能保持在82%。
Abstract: Well-defined ordered ZnO nanorod arrays were successfully prepared on activated carbon fibers by combining sol-gel with a hydrothermal method. The growth mechanism was proposed by SEM, XRD and N2 physisorption. Concentration of zinc acetate had a regulatory effect on the morphology of ZnO nanorods. ZnO films provided the nucleus for oriented growth of nanorods, promoting its preferential growth along the c-axis direction of activated carbon fibers. The photocatalytic tests showed the catalytic performance of ZnO nanorod arrays/activated carbon fibers was influenced obviously by zinc acetate. When the Zn(CH3COO)2 concentration was 0.15 mol∙L−1, its removal effi-ciency of methylene blue reached 90% during 120 min. After five regeneration cycles, its photo-catalytic efficiency remained 82%.
