Hydrothermal synthesis and effects on morphology of micro-/nanomaterials of hexagona β-Co(OH)_2

The hexagonal single-platelike or muti-platelikeβ-Co(OH) 2 have been successfully synthesized by changing the reaction condition through a simple surfactant-free and hydrothermal method.Under a suitable reaction condition,the perfect single-layer hexagonalβ-Co(OH) 2 platelets with highly crystalline nature can be obtained.The structure and morphology of the resultant products were characterized by using XRD,FESEM,TEM,HRTEM and Selected-Area Electron Diffraction(SAED) .The results show that the morphology and structure of the obtained products can be strongly influenced by changing the reaction condition,such as:Co(NO3) 2 concentrations,reaction temperature and composition of solutions(addition of isopropyl alcohol) .
