摘　　要：利用水热法在不锈钢丝网上制备了氧化锌纳米线阵列,借助扫描电镜(SEM)对产物的形貌进行了表征,探讨了反应物浓度和反应时间对产物形貌的影响,并以橙黄Ⅱ为目标降解物,研究了不同生长条件下氧化锌纳米线阵列的光催化降解性能。研究结果表明:硝酸锌浓度和反应时间对氧化锌纳米线阵列的密度、长度、直径和晶形有重要影响,在硝酸锌浓度为0.1 mol/L、反应时间为6 h条件下,制得的氧化锌纳米线阵列具有较佳的光催化活性,多次循环实验结果表明其稳定性较高。另外,双层叠合的氧化锌纳米线的光催化降解性能优于单层氧化锌纳米线的实验结果,其不锈钢丝网的网状结构为制备多维纳米阵列和薄膜提供了一种新的研究思路。ZnO nanowire arrays were successfully fabricated on stainless steel mesh by hydrothermal method. The surface morphology of as-synthesized samples were characterized by scanning electron microscopy （SEM）.The effects of reactants＇ concentration and reaction time on the morphology were discussed in detail.The photocatalytic activities of various ZnO nanowire arrays under different conditions have been studied by degradation of acid orange II .The results showed that the density,length, diameter, and morphology of the ZnO nanowire arrays were significantly influenced by the concentration of zinc nitrate and reaction time.Under the conditions of zinc nitrate concentration of 0.1 mol/L and reaction time of 6 h ,the obtained products showed better photocatalytic activity,which can be reused and exhibited high stability.In addition,the photocatalytic degradation test results of laminated ZnO nanowire arrays confirmed that the latticed structure of the stainless steel mesh provided a novel route for the multi-dimension nanoarrays and nanofilms.
