| 摘 要： | 以ZnSO4.7H2O和NaOH为主要原料,通过简单的一步水热合成路线,制备出平均直径为100～200 nm,长度为2.0～3.0μm,沿0001]方向择优生长的ZnO纳米棒.利用XRD、SEM和紫外可见光吸收光谱研究了OH-浓度和水热反应时间对产物形貌及光催化活性的影响.研究结果表明,所获得的ZnO纳米棒对亚甲基蓝具有良好的光催化活性,通过调整OH-浓度和水热反应时间可以实现ZnO纳米棒的可控合成,OH-浓度和水热反应时间对产物的形貌和光催化活性影响显著.

| Abstract: | ZnO nanorods with 100~200nm in diameter and 2.0~3.0μm in length along orientation were prepared with simple one-step hydrothermal method using ZnSO4·7H2O and NaOH as reactants.Effects of OH-concentration,reaction time on the morphology and photocatalytic properties of products were investigated by X-ray diffraction,scanning electron microscopy and UV-vis absorption spectra.The results show that ZnO nanorods have good photocatalytic properties to methylene blue trihydrate and the controllable synthesis can be achieved by altering OH-concentration and reaction time.OH-concentration and reaction time have great influence on the morphology and photocatalytic properties of products. |
