The amino acids have extensive applications, and their productions from biomass‐derived feedstocks are very attractive. In this work, the synthesis of amino acids by amination of bio‐derived hydroxy acids with ammonia over different metallic nano‐catalysts supported on various supports is studied. It is found that Ru nano‐catalysts on the nitrogen‐doped carbon nanotubes (Ru/N−CNTs) have an outstanding performance for the reaction. Different hydroxy acids can be catalytically converted into the corresponding amino acids with yields up to 70.0 % under mild conditions, which is higher than those reported. The reasons for the high efficiency of the catalyst are investigated, and the reaction pathway is proposed on the basis of control experiments.
