AB - A series of NixIny-BTC metal organic frameworks (x/y denotes the Ni/In atomic ratio) were prepared through the solvothermal method, and then carbonized at 400–700 °C in a N2 flow followed by the H2 reduction at 550 °C to prepare carbon-coated Ni–In IMCs catalysts. It has been found that the H2 reduction is favorable for the formation of Ni–In IMCs and the Ni–In IMCs phases in NixIny@C are determined by the Ni/In atomic ratio. Interestingly, a thin layer of carbon (~ 2 nm) coats the Ni–In IMC particles. NiIn3C0.5 IMC forms in Ni2In1@C, and its crystallite size increases with carbonization temperature. In addition, raising the carbonization temperature promotes the degree of graphitization. In in-situ aqueous phase selective hydrogenation of methyl palmitate to hexadecanol using methanol as hydrogen donor, all the NiIn3C0.5 IMC, NiIn IMC and Ni2In3 IMC dominatingly give hexadecanol, however, Ni2In3 IMC is hydrothermally unstable. Therein, Ni2In1@C carbonized at 600 °C (i.e., Ni2In1@C-600/550) exhibits the best performance with the hexadecanol yield of 90.3%, and the hexadecanol yield maintains ~ 90% during 5 times recycling. Such high activity and stability are ascribed to stable NiIn3C0.5 IMC phase, thin carbon layer and suitable degree of graphitization in Ni2In1@C-600/550.
