摘要
在不添加表面活性剂,无模板的情况下,以钼粉和双氧水为原料,采用90℃水浴的方法制备三氧化钼纳米带。用X-射线衍射(XRD),扫描电子显微镜(SEM),透射电子显微镜(TEM)对产物进行表征。结果表明,反应产物均为三氧化钼纳米带,且纳米带尺寸均匀,宽度为80～100nm,厚度为20nm,长度为5～30μm。研究还发现,合成条件如反应时间,反应介质对产物的形貌有一定影响。
MoOa nano-belts have been Mo power and H2O2 as precursors in synthesized at 90℃ by a facile water bath using the absence of any surfactants and templates. The products are characterized by X-ray diffraction （XRD）, scanning electron microscopy （SEM） and transmission electron microscopy （TEM）. The results show that the as-pre pared products are composed of MoO3 nano-belts with uniform sizes. The nano-belts are 80--100 nm in width, 20 nm in thickness and 5-30μm in length. It is found that the morphologies of MoO3 nano-belts can be changed by adjusting the synthetic parameters, such as reaction times and medium.
