摘要：

Room temperature glow discharge plasma was applied to treat the nickel precursor supported on SiO2. According to the catalyst characterization, the calcination thermally of the plasma treated sample shows small particle size and high dispersion. Such prepared sample presents high conversions of carbon monoxide and hydrogen for the reaction of methanation with a significantly improved anti-carbon deposition performance. The plasma-treated sample shows enhanced metal-support interaction and keeps good dispersion after reaction.
