Controlled Hydrothermal Synthesis Of Vo_2(b) Nanobelts

摘要

Large-scale VO_2(B) nanobelts have been synthesized by hydrothermal strategy via one-step method using V_2O_5 as vanadium source and C_6H_5-(CH_2)_n-NH_2 with n = 2 and 4 (2-phenylethylamine and 4-phenylbutylamine) as structure-directing templates. The composition and morphology of the nanobelts were established by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). The as-obtained VO_2(B) nanobelts have a length of 3-10 μm, a wideness of 100-375 nm and a thickness of 30-66 nm.
