Herein we report an efficient and recyclable system for tandem CO2 capture and hydrogenation to methanol. After capture in an aqueous amine solution, CO2 is hydrogenated in high yield to CH3OH (>90%) in a biphasic 2-MTHF/water system, which also allows for easy separation and recycling of the amine and catalyst for multiple reaction cycles. Between cycles, the produced methanol can be conveniently removed in vacuo. Employing this strategy, catalyst Ru-MACHO-BH and polyamine PEHA were recycled three times with 87% of the methanol producibility of the first cycle retained, along with 95% of catalyst activity after four cycles. CO2 from dilute sources such as air can also be converted to CH3OH using this route. We postulate that the CO2 capture and hydrogenation to methanol system presented here could be an important step toward the implementation of the carbon neutral methanol economy concept.

使用可重复使用的催化剂和胺将 CO2 捕集和加氢合成甲醇：迈向碳中和甲醇经济

在此，我们报告了一种高效且可回收的系统，用于串联 CO2 捕获和加氢制甲醇。在胺水溶液中捕获后，CO2 在双相 2-MTHF/水系统中以高产率氢化成 CH3OH (>90%)，这也允许轻松分离和回收胺和催化剂用于多个反应循环。在循环之间，产生的甲醇可以方便地真空除去。采用这种策略，催化剂 Ru-MACHO-BH 和聚胺 PEHA 被循环使用 3 次，第一次循环的甲醇生产能力保持在 87%，四次循环后催化剂活性保持在 95%。来自稀释来源（如空气）的 CO2 也可以使用此途径转化为 CH3OH。
