Abstract: Single crystal orthorhombic phase MoO3 (α-MoO3) 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 h-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-MoO3 nanobelts.
