摘要

使用不同的镍前驱体制备了镍/CeO2 催化剂，并对氧化氮制氨反应进行了检验。与其他镍前驱体相比，用醋酸镍制备的催化剂显示出更高的活性。这些催化剂的理化性质和催化活性表明，醋酸镍前驱体高度分散在 CeO2 表面，并表现出强烈的金属-支撑相互作用，这可能是催化活性高的原因。

Effect of Ni precursors on the catalytic activity of Ni/CeO2 for nitrogen oxide to ammonia reaction

Ni/CeO₂ catalysts was prepared using different Ni precursors and examined for nitrogen oxide to ammonia reaction. The catalyst prepared from nickel acetate showed higher activity than that of other Ni precursors. The physiochemical properties and catalytic activity of these catalysts revealed that nickel acetate precursor was highly dispersed on the surface of CeO₂ and showed strong metal-support interactions which may be responsible for high catalytic activity.
