Received Date: 25 December 2006

A novel K₂O and La₂O₃ promoted nickel catalyst supported on α-Al₂O₃ was prepared by co-impregnation method, and it exhibited higher activity and 6-aminocapronitrile selectivity than Ni/α-Al₂O₃ during the hydrogenation of adiponitrile in the absence of ammonia, i.e., K₂O and La₂O₃ improved the performance of the nickel-based catalyst.
