Palladium nanoparticles immobilized on alkylated triazine COFs have been prepared. Caging effect of triazine COF was able to stabilize Pd nanoparticles by the coordination of Pd toward nitrogens in triazine COF. Alkyl chain can adsorb starting organic compound by the hydrophobic interaction and accelerate Suzuki-Myaura coupling reaction. Through the introduction of hydrophobic alkyl chain to melamine moiety, an efficient heterogeneous catalytic reaction was successfully carried out under aqueous ethanol system. The synthesized catalyst showed recyclability with negligible leaching of Pd. Various characterization techniques including XPS, ICP-MS, SEM, BET, XRD, TEM, 1H- and 13C- NMR are used to verify the efficiency of the catalyst. |
