AbstractMesoporous NiO is synthesized with a fast and facile method by using octylamine (OA) and NiCl2 center dot 6H(2)O as template and precursor, respectively. The resultant products are characterized with XRD, DRIFT, SEM, TEM, XPS and nitrogen adsorption-desorption measurements. The synthesis approach is described by the S+X-I+ (OA(+)Cl(-)Ni(2+)) assembly pathway, where the process is mediated by the addition of HCl. The reaction takes place at room temperature and completes in an hour, where the addition of NaOH solution leads to rapid precipitation of Ni(OH)(2) and formation of partially ordered mesopores. Nanocrystalline mesoporous NiO is obtained after removal of template and decomposition of Ni(OH)(2) upon hot ethanol washing and calcination. The mesopores in NiO are built from the embedded nanocrystallites through template removal and calcination induced cracking. The NiO product achieves a high surface area of 350 m(2)/g after 300 degrees C/3 h calcination. The effects of synthetic conditions on the properties of NiO are addressed. (C) 2012 Elsevier Inc.
