中文摘要：
以HCl和Na2MoO4·2H2O为原材料,不用任何模板剂的情况下,用简单的水热法成功地制备了正交相单晶α-MoO3纳米带。用X射线衍射仪、扫描电子显微镜、透射电子显微镜、紫外-可见光分光光度计对产物进行了表征。结果显示,α-MoO3纳米带是由低温条件下形成的亚稳相h-MoO3微米棒通过溶解-重结晶转变而来,其沿着c轴方向生长,加入表面活性剂CTAB可以提高α-MoO3纳米带的长径比。
英文摘要：
Single crystal orthorhombic phase MoO3 （α-MoOa） nanobelts with uniform diameter were successfully prepared through a simple hydrothermal synthesis route at 180℃, using solution of sodium molybdate dihydrate as well as hydrochloric acid as raw materials and without template. The products were characterized by X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. It can be concluded that the synthesized α-MoO3 nanobelts were transformed from the metastable phase α-MoO3 micro rods formed at low temperature （-90℃） by dissolution-recrystallization, and grew along the c-axis direction. Surfactant CTAB could increase aspect ratio of the prepared α-MoOa nanobelts.
