Biomimetic Formation of Pd and Au-Pd Nanocomposites and their Catalytic Applications

摘要

In this work, we probed the formation of gallic acid (GA) assemblies. It was observed that nanoassemblies of varying morphologies were formed depending upon the growth conditions. We then utilized the assemblies as templates for the growth of palladium (Pd) nanoparticles for developing catalytic systems biomimetically. Further, amide conjugates of GA were synthesized and self-assembled for the formation of uniformly coated assemblies of Pd nanoparticles and Au-Pd nanocomposites. Their catalytic abilities were explored by examining the degradation of para-nitrophenol. Thus, we have developed a new class of nanocomposites that were found to be effective catalytic nanomaterials via green synthesis.
