Abstract:A novel plasma-treated Ni/MgO catalyst was prepared by treating coprecipitated NiCO3-MgCO3 with dielectric-barrier discharge plasma. The results by XRD, TEM and N-2 adsorption analyses showed that the plasma-prepared Ni/MgO catalyst possessed smaller particle size, enhanced nickel dispersion, and higher specific surface area than a conventionally reduced Ni/MgO catalyst. The plasma-prepared Ni/MgO catalyst also exhibited better catalytic activity for carbon dioxide reforming of methane. More than 20% higher conversions of methane and carbon dioxide were obtained than those over the conventional Ni/MgO catalyst at 700 degrees C and a space velocity of 96,000 mL/(h.g(cat)).
