제목 Green synthesis and characterization of palladium nanoparticles and their catalytic application in multicomponent reaction
초록 Palladium nanoparticles (PdNPs) were synthesized using green method. An aqueous extract of Perilla frutescens leaf was used as a bioreductant to reduce Pd2+ ions to Pd0. Polyphenols and flavonoids are believed to be actively involved in the reduction process. The formation of PdNPs was confirmed by UV-Vis spectra. Transmission electron microscopy revealed spherical nanoparticles, ranging in size between 10 and 17 nm (average ~13 nm). X-ray diffraction confirming the crystallinity of the nanoparticles with a face centred cubic (fcc) structure. Energy dispersive X‒ray spectroscopy confirmed the presence of palladium. Fourier transform infrared spectroscopy suggested the role of polyols present in the P. frutescens leaf extract. The synthesized nanoparticles were used as a catalyst for the synthesis of pyrazolylphosphonate derivatives in high yield. The excellent catalytic performance of the synthesized PdNPs can be associated to their extremely small size and high dispersity.
