Methanation of carbon dioxide (CO₂) is attractive within the context of a renewable energy refinery. Herein, we report an indirect methanation method that harnesses amino alcohols as relay molecules in combination with a catalyst comprising ruthenium nanoparticles (NPs) immobilized on a Lewis acidic and robust metal–organic framework (MOF). The Ru NPs are well dispersed on the surface of the MOF crystals and have a narrow size distribution. The catalyst efficiently transforms amino alcohols to oxazolidinones (upon reaction with CO₂) and then to methane (upon reaction with hydrogen), simultaneously regenerating the amino alcohol relay molecule. This protocol provides a sustainable, indirect way for CO₂ methanation as the process can be repeated multiple times.

采用钌纳米颗粒/金属有机框架催化剂通过氨基醇中继分子进行二氧化碳甲烷化。

二氧化碳（CO ₂ ）的甲烷化在可再生能源精炼厂的背景下很有吸引力。在此，我们报告了一种间接甲烷化方法，该方法利用氨基醇作为中继分子，与包含固定在路易斯酸性和坚固的金属有机框架（MOF）上的钌纳米颗粒（NP）的催化剂相结合。 Ru NPs 很好地分散在 MOF 晶体的表面，并且具有较窄的尺寸分布。该催化剂有效地将氨基醇转化为恶唑烷酮（与CO ₂反应后），然后转化为甲烷（与氢气反应后），同时再生氨基醇中继分子。该方案为CO ₂甲烷化提供了一种可持续的、间接的方式，因为该过程可以重复多次。
