Abstract
Nickel hydroxide is formed on the surface of porous carbon matrix as a result of decomposition of nickel ammine at a temperature of 90 °C in an open-type reactor under intense mixing of the reaction mixture. Porous carbon material obtained by means of high temperature carbonization of hydroquinone - furfurol mixture was used as a matrix. The result is the formation of nanostructured composite filled with the crystallites of anhydrous Ni(OH)2. Studies by means of X-ray diffraction and small-angle scattering of X-ray radiation showed that nickel hydroxide crystallites formed on the surface of carbon matrix have smaller size than the crystallites formed in solution without any matrix.
