Abstract:
Various morphologies of cobalt hydroxides have been successfully prepared from cobalt nitrate with the assistance of dimethylglyoxime in water/ethanol solutions by hydrothermal processing at 220 C The crystalline products are he) agonal phase of beta-cobalt hydroxide and the crystallinity Increases as the volume ratio of water to ethanol rises Hexagonal plate like broom-like or straw bundle-like and grass-like cobalt hydroxides are obtained with water to ethanol ratios of 1 0 2 1 and 1 2 respectively The novel bundle-like assemblies are further constructed from lots of nanobelts which mainly grow along 11001 direction and evolve from less-crystalline disc like structures and semi-crystalline flower-like assemblies as the hydrothermal time extend (C) 2010 Elsevier B V All rights reserved
