Abstract A novel trimetal-oxides (Ru/Fe/Ce) supported on γ-Al2O3 catalyst was synthesised by simple impregnation method and the activity was investigated at atmospheric pressure. The results showed that Ru/Fe/Ce (5:10:85)/γ-Al2O3 catalyst calcined at 1000 °C for 5 h was effective and gave a 97.20% of CO2 conversion at 275 °C with 93.5% of CH4 formation. The catalyst possesses medium-strength basic sites with the best reduction temperature of

Ru/Fe/Ce/γ-Al2O3 催化剂纳米颗粒异质结构上的催化甲烷化：性能和表征

摘要 采用简单的浸渍法合成了γ-Al2O3 催化剂负载的新型三金属氧化物(Ru/Fe/Ce)，并在常压下对其活性进行了研究。结果表明，Ru/Fe/Ce (5:10:85)/γ-Al2O3 催化剂在 1000 °C 下煅烧 5 h 是有效的，在 275 °C 下 CO2 转化率为 97.20%，CH4 形成率为 93.5%。该催化剂具有中等强度的碱性位点，最佳还原温度为
