One dimensional WO3 nanowires with high aspect ratio of >200 were synthesized by hydrothermal method. The effects of reaction temperature and time on phase and morphologies were studied and discussed. In this research, a suitable hydrothermal condition is at 200°C for 48 h. XRD, SEM, and TEM results show that the product is hexagonal WO3 phase with diameter of 25 nm and several ten micrometers long with growth in the c direction. The electrochemical properties were tested for rechargeable lithium batteries. The WO3 NWs electrode exhibits a stability trend over the 30 cycle testing. Some long-term activation process is attributed to the WO3 NWs electrode during charge/discharge reaction.

Uniform α-MoO3 nanobelts were successfully synthesized by the hydrothermal process at 180°C for 20 h of the acidic solutions with different
pH values of 0–0.75, adjusted using HCl (conc.). XRD and SEM results revealed that the pH of the precursor solutions played
an important role in the phase, impurities, and morphology of the products. At the pH=0, the perfect α-MoO3 nanobelts with a few tens of microns long were synthesized. By the TEM characterization, orthorhombic MoO3 has a distinctive layered structure along the [010] direction, consisting of distorted MoO6 octahedrons connected by common corners along the [100] direction and common edges along the [001] direction. The electrochemical
measurement showed that the α-MoO3 nanobelts have high specific charge capacity. 相似文献

Different morphologies of ZnO structures were successfully synthesized in precursor solutions with the pH of 8, 9, 10, 11, and 12 by a sonochemical method at room temperature. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier Transform Infrared (FTIR) and Raman spectroscopy. The photocatalytic activities of ZnO samples with different morphologies were evaluated via the degradation of methylene blue (C16H18ClN3S). In this research, the flower-like ZnO sample of densely assembled nanoplates exhibited the highest photodegradation of 64% under UV light irradiation within 300 min. 相似文献

Orthorhombic molybdenum trioxide (α-MoO3) nanobelts have been successfully synthesized by hydrothermal method at 180°C for 20 h. The prepared α-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 α-MoO3 nanobelts grow along the c-axis, with ±(100) top or bottom surfaces and ±(010) side surfaces. The prepared α-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. 相似文献
