应用室温辉光放电等离子体来处理负载在SiO 2 上的镍前体。根据催化剂表征，等离子体处理后的样品热煅烧显示出小粒径和高分散性。这样制备的样品呈现出用于甲烷化反应的一氧化碳和氢气的高转化率，并具有显着改善的抗积碳性能。等离子体处理的样品表现出增强的金属-载体相互作用，并在反应后保持良好的分散性。
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.
