制备三氧化钼纳米带的一种新方法

A New Method of Synthesis of MoO_3 Nanobelts

在不添加表面活性且无模板的条件下,以钼粉和双氧水为原料,在不同温度、时间等条件下制备了三氧化钼纳米带;用X射线衍射仪、扫描电子显微镜、透射电子显微镜等对产物进行了表征。结果表明:90℃时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,长度为数十微米;合成时反应温度和介质等对产物的形貌均有一定的影响。

MoO3 nanobelts were synthesized at different temperatures for different reaction times, using Mo powers and H2O2 as raw materials in the absence of any surfactants and templates. The products were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The results show that the prepared products were composed of MoOa nanobelts with uniform sizes. The nanobelts were 80-100 nm in width, 20 nm in thickness and several tens of micrometres in length. It was found that the morphology of MoO3 nanobelts could be influenced by adjusting the technology parameters, such as reaction temperature and medium.
