摘要：

Orthorhombic molybdenum trioxide (alpha-MoO3) nanobelts have been successfully synthesized by hydrothermal method at 180A degrees C for 20 h. The prepared alpha-MoO3 samples were investigated by X-ray diffraction, Fourier transform IR spectroscopy, Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy methods. It was found that alpha-MoO3 nanobelts grow along the c-axis, with +/-(100) top or bottom surfaces and +/-(010) side surfaces. The prepared alpha-MoO3 nanobelts were used as cathode materials for Li-ion batteries. They exhibit specific capacity of 1340 and 1250 mA h g(-1) at a current density of 100 and 400 mA/g, respectively.
