NOVELTY - Preparing copper-containing catalyst comprises (1) adding precursor in organic solvent, preparing metal nano-particle colloid by pyrolysis, (2) adding porous carrier into metal nano-particle colloid obtained in step (1) for dipping, dipping for 0.5-2 hours under the action of electrostatic field, dipping for 3-20 hours under the action of no electrostatic field, drying for 6-24 hours at 60-120degrees Celsius to obtain the copper-containing catalyst, where the porous carrier is graphene, graphite alkyne, activated carbon fibers (ACF) and active carbon. The precursor is manganese cuprate and selenide auxiliary agent with average grain diameter nano level and in the copper-containing catalyst the copper load amount is 1-30 wt.%, the selenide load amount is 0.1-2 wt.%. USE - The copper-containing catalyst is useful in alkyne hydrochlorination reaction, preferably alkyne is C2-C4 alkyne, more preferably acetylene or propyne. ADVANTAGE - The catalyst has high catalytic activity and stability.
