Carbon Foam as a Support for Palladium Catalysts for Selective Hydrogenation of 2-Butyne-1,4-diol

Key Points

• This research aims to evaluate carbon foam as a support material for palladium catalysts in selective hydrogenation reactions.
• Synthesize open-cell carbon foam from hydrocarbon gas pyrolysis products.
• Modify carbon foam by depositing pyrolytic carbon layers to enhance strength and reduce defects.
• Disperse palladium particles using pyrolytic carbon-supported palladium polyhydroxo complexes.
• The modified carbon foam shows reduced surface defects and maintains its open-cell structure.
• Uniformly dispersed palladium particles on the carbon surface enhance catalytic performance.
• The developed catalyst effectively facilitates the selective hydrogenation of 2-butyne-1,4-diol to 2-butene-1,4-diol.
