چکیده انگلیسی
Nanocrystalline NiO with a coral-like structure (38â¯nm) has been prepared via thermal decomposition of a new precursor, nickel galactarate (NiC6H8O8·2H2O), at 500â¯Â°C for 3â¯h in air. Thermal decomposition of that precursor was studied by TG and DSC techniques. The resultant NiO was physicochemically characterized by XRD, FTIR, SEM, surface area, porosity and CO2-TPD. NiO was found to exhibit a remarkable activity towards the synthesis of MEK from 2-butanol between 200 and 325â¯Â°C. In addition, it has shown a great tendency to ease regeneration of the used catalyst after 192â¯h in stream by simple refreshing method.
