A catalyst for a hydrogenation reaction including: a polymer support; and a catalytic component supported on the polymer support. The polymer support comprises a repeating unit represented by Formula 1.
First claim
Opening claim text (preview).
1 . A catalyst for a hydrogenation reaction, the catalyst comprising: a polymer support; and a catalytic component supported on the polymer support, 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. 2 . The catalyst of claim 1 , wherein Formula 1 is represented by any one of Formulae 2 to 9: 3 . The catalyst of claim 1 , wherein the catalytic component comprises one or more of platinum, palladium, ruthenium, iron, nickel, cobalt, molybdenum, gold, silver, copper, titanium, gallium, cerium, aluminum, zinc, and lanthanum. 4 . The catalyst of claim 1 , wherein an amount of the catalytic component is 0.01 wt % to 10 wt % based on a total weight of the catalyst. 5 . The catalyst of claim 1 , wherein the catalyst is a catalyst for a hydrogenation reaction of alkyne to alkene. 6 . A method for manufacturing a catalyst for a hydrogenation reaction, the method comprising: preparing a polymer support comprising a repeating unit represented by Formula 1; and supporting a catalytic component on the polymer support: 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. 7 . The method of claim 6 , wherein Formula 1 is represented by any one of Formulae 2 to 9: 8 . The method of claim 6 , wherein the catalytic component comprises one or more of platinum, palladium, ruthenium, iron, nickel, cobalt, molybdenum, gold, silver, copper, titanium, gallium, cerium, aluminum, zinc, and lanthanum. 9 . The method of claim 6 , wherein an amount of the catalytic component is 0.01 wt % to 10 wt % based on a total weight of the catalyst.
