Abstract:
Disclosed are a selective hydrogenation catalyst, a preparation method therefor and a use thereof, which belong to the technical field of catalysts. The selective hydrogenation catalyst comprises an active component and a carrier supporting the active component, wherein the active component is transition metal particles; and the carrier is pre-modified with a flexible chain ligand, one end of which is evenly distributed on the surface of the carrier, and the other end of which is coordinated on the transition metal.
