There is interest in development of “one pot” syntheses of fixed carbon bed catalysts in which a metal precursor complex is included with the carbon precursors that polymerize to give a porous polymer that is then converted by heating under an inert atmosphere into porous carbon incorporating nickel nanoparticles. This approach was explored using a newly synthesized cyclohexyl salen ligand (1) to incorporated nickel into/on the carbon support. Physical characterization by SEM, XRD, gas adsorption and electrical conductivity was carried out, and the catalytic activity for the hydrogenation of furfural was evaluated. SEM showed the formation of nickel nanoparticles in carbon pyrolyzed to 500 oC, with growth of the particles for carbon samples pyrolyzed to 800 oC. The catalytic activity showed the opposite trend; the samples catalyzed to 800 oC were found to give higher conversion than those at 500 oC. The causes of this unusual behavior will be addressed.
