| Abstract: | A Ni/MgO catalyst was prepared using atmospheric high frequency discharge plasma jet. The influence of three preparation meth-ods,the conventional method,plasma method,and plasma plus calcination method,on the catalyst activity was compared using CO2 reform-ing with methane as the probe reaction. The catalyst samples were characterized by X-ray diffraction,transmission electron microscopy,X-ray photoelectron spectroscopy,and CO2 temperature-programmed surface reaction. The results suggested that the Ni-base... |
