Binary Roles of Schiff Bases as Capping Agent and Precursor for Synthesis of Metallic Nickel Ultrafine Nanoparticles

چکیده مقاله

This study focused on the synthesis and characterization of nickel nanoparticles by simple precipitation method. The various Schiff bases such as ethylenediamine (acacen), 1,3-propylenediamine (acacpn), and butane-1,4-diamine (acacbn) acetyl acetonate were prepared and were used for preparing of nickel-Schiff base complexes and then, these complexes as precursor were reduced in the presence of KBH4, for the first time. In addition, the anti-aggregation effect of prepared Schiff bases was compared with common surfactants and results demonstrated that the huge ligands can be considered as novel surfactants. The obtained nickel nanoparticles were characterized by XRD, TEM, HRTEM, FT-IR, SEM, and EDS.
