NOVELTY - Preparing non-noble metal nickel-copper catalyst comprises depositing required amount of copper precursor on carrier by atomic layer deposition method for one time or multiple times at 80-400 degrees C, then introducing reducing agent to convert the copper precursor into an auxiliary agent copper to obtain load type catalyst precursor, depositing required amount of nickel precursor on a supported catalyst precursor by atomic layer deposition method for one or multiple times at 80-400 degrees C, and then introducing an oxidant to convert the nickel precursor into an active component, and obtaining a nickel-copper supported catalyst, optionally, processing the obtained nickel-copper supported catalyst by reducing agent at 200-400 degrees C, where catalyst comprises carrier, auxiliary agent and the active component, and the carrier is at least one of graphitic carbon nitride (g-C3N4), nitrogen-doped activated carbon, nitrogen-doped graphene and nitrogen-doped carbon nano-tube. USE - The catalyst is useful in selective hydrogenation reaction of acetylene or 1,3-butadiene in monoolefin-rich atmosphere. ADVANTAGE - The catalyst is carbon deposition resistant, has high-selectivity and catalytic performance in selective hydrogenation reaction of acetylene or 1,3-butadiene in monoolefin-rich atmosphere, and can completely inhibit the production of green oil and carbon deposit and maintain the stability for more than 350 hours in the hydrogenation reaction.
