- Abstract
The β-Ni(OH) platelets and nanorods with length ranging from 2 to 6 μm have been successfully synthesized via a hydrothermal method, and no templates or additives were employed. The products were characterized by X-ray powder diffraction and scanning electron microscopy techniques. The dosage of sodium hydroxide and temperature were found to play important roles in controlling the size and morphology of β-Ni(OH). The shape of β-Ni(OH) platelets was successfully sustained during the thermal transformation to NiO. Optical property of the NiO platelets was investigated by means of UV-Vis spectrum, exhibiting small red shift compared to the bulk counterpart. Such β-Ni(OH) and NiO microstructures may find potential applications in micro/nano-devices.
