Summary Modified nickel‐boride (Ni‐B)‐based amorphous alloy catalysts used for microwave‐assisted catalytic transfer hydrogenation (CTH) of fatty acid methyl esters (FAMEs) had been synthesized via chemical reduction method by adding simultaneously cetyltrimethylammonium bromide (CTAB) and various transition metals. The results suggested that Cr‐doped Ni‐B‐CTAB catalyst showed superior catalytic activity. It was found that Ni‐Cr‐B‐CTAB catalyst remained an amorphous structure and had a smaller particle size with less agglomeration as compared with Ni‐B catalyst. What's more, the specific surface area of the catalyst increased obviously with the addition of CTAB and Cr into Ni‐B catalyst. Under the established optimum conditions of CTH using Ni‐Cr‐B‐CTAB as a catalyst, the conversion ratio of methyl linoleate reached 78.05% and the properties of hydrogenated FAMEs were improved obviously. This work has provided a feasible approach to prepare a new and efficient Ni‐Cr‐B‐CTAB amorphous alloy catalyst for the CTH of FAMEs and thus to obtained the high‐quality hydrogenated FAMEs.
