摘要

•MOFs-derived Ni-Co alloy catalysts were used in NCH selective hydrogenation.•Ni-Co alloy effects facilitate CoOx reduction and increase the Co0 amounts.•Ethylenediamine favors the N-CHH formation and reduces the whole energy barriers.•Pyridinic-N favors intermediate N-CHH conversion to CHO.•Ni1Co2 (111) crystal surface presents the lowest energy barrier of the α-H transfer.
