Synthesis of nanoparticles of Pd(II) complexes containing triazole and tetrazole derivative ligands and corresponding metal-nano oxides by sonochemical method

Abstract

In this research, nanoparticles of the (1) [PdCl2(aemptrz)], and (2) [Pd2(μ-mmtz)4].2CH3CN, have been synthesized using ultrasonic waves in the ultrasonic bath (sonochemistry method, which is one of the methods of liquid state processing) at constant temperature and different times. Both complexes were analyzed using (XRD) and (FTIR) techniques. Nanoparticles of PdO, prepared by calcination in an electric furnace and characterized by (FESEM), (XRD), and (FT-IR) techniques. The results of XRD analysis showed that the synthesized PdO nanoparticles (resulting from nano complexes 1 and 2) crystallized in the space group P42/mmc of the tetragonal (for 1) and P2/c space group of the monoclinic (for 2) systems. The results of the FESEM micrographs showed that the size of the synthesized PdO particles derived from nano complex (1) and (2) is between 35.44 - 61.36 and 34.21 - 67.69 nm, respectively.
