The production of amine intermediates from biomass is capturing increasing attention. Herein, an efficient conversion of furfural to furfural amine over RuCo/AC catalyst under hydrothermal conditions has been investigated. The effects of different carriers, bimetals, and reaction conditions were systematically investigated in green solvents (water). Fully conversion of furfural and high furfural amine yield (92.13%) at 80 ℃ for 1 h over 4Ru1Co/AC. The excellent catalytic performance of 4Ru1Co/AC was attributed to its high acidity and good hydrogenation ability, as well as the synergistic effect between Ru-Co alloy formations and the activated carbon. Importantly, the highly selective preparation of furfural to furfural amine is a promising way to high-value utilization of cellulosic biomass in green solvents.

从生物质中生产胺中间体越来越受到关注。在此，研究了在水热条件下通过 RuCo/AC 催化剂将糠醛有效转化为糠醛胺。在绿色溶剂（水）中系统地研究了不同载体、双金属和反应条件的影响。在 4Ru1Co/AC 条件下，80 ℃ 1 h 糠醛完全转化，糠醛胺收率高（92.13%）。4Ru1Co/AC优异的催化性能归因于其高酸性和良好的加氢能力，以及Ru-Co合金形成与活性炭之间的协同作用。重要的是，糠醛到糠醛胺的高选择性制备是在绿色溶剂中高价值利用纤维素生物质的有前景的方法。
