Ni-Co-oxide hollow sphere were synthesized in a simple one-pot synthesis via a hydrothermal approach, using urea and carbohydrate as precipitating and structure directing agents respectively. Prepared materials were characterized by using various techniques, such as scanning electronic microscopy (SEM), X-ray diffraction spectroscopy (XRD). Mixed metal oxides displayed excellent catalytic activity with hydrogen generation rate of 603 ml g-1 min-1 and low activation energy; further more catalyst could be reused at least four times without any appreciable loss in catalytic activity. |
