Catalyst for hydrogenation reaction and method for producing same

A method for manufacturing alkene, the method comprising:

• hydrogenating alkyne under a catalyst for a hydrogenation reaction to manufacture alkene,
• wherein the catalyst comprises a polymer support and a catalytic component supported on the polymer support, and
• wherein the polymer support comprises a repeating unit represented by Formula 1:
• wherein in Formula 1,
• R1 to R4 are the same as or different from each other, and are each independently hydrogen, an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 20 carbon atoms, or adjacent groups optionally bonded to each other to form a hydrocarbon ring.
