We investigate aggregation process of the Ni(OH) 2 under hydrothermal condition. The samples are characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The results show that the self-assembled Ni(OH) 2 nanosheets with the hexagonal structure is about 30 nm in thickness. We investigate the effect of reaction temperature on the morphology of the product. The nanosheets can aggregate together when the temperature and reaction time are suitable. And a possible mechanism is also proposed to explain the growth and aggregation process of Ni(OH) 2 nanosheets.
