Abstract: Nickel oxide (NiO) microsphere with a large surface area was novelly synthesized through nickel bicarbonate (Ni(HCO3)2) precursor. The obtained nickel oxide (NiO) microsphere was characterized by X-ray pattern diffraction, scanning electron microscopy, CO2 temperature-programmed desorption, H2 temperature-programmed reduction, N2 adsorption/desorption and laser scattering particle size distribution analyzer. It was found that nickel oxide (NiO) synthesized by the thermal decomposition of Ni(HCO3)2 through area hydrolysis, presented very nice microsphere with high surface area. The catalytic properties of obtained nickel oxide (NiO) microsphere were studied in the reaction of carbon dioxide reforming of methane where 91.3% conversion of CH4 with 93% conversion of CO2 was observed. Besides, the catalyst maintained high stability over 200 h on the stream.
