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 ~3.0um in length along [0001 ]orientationwere prepared with simple one-step hydrothermal method using ZnSO, · 7H,0 and NaOH as reactants. Efectsof OH" concentration , reaction time on the morphology and photoeatalytic properties of products were investi-.gated by X-ray diffraction, scanning electron microscopy and UV-vis absorption spectra. The results show thatZn0 nanorods have good photocatalytie properties to methylene blue trihydrate and the controllable synthesiscan be achieved by altering OH" concentration and reaction time. OH" concentration and reaction time havegreat influence on the morphology and photocatalytic properties of products.
