A PROCESS FOR THE POLYETHYLENIMINE AND ORGANIC REDUCING AGENT -MEDIATED SYNTHESIS OF NOBLE METAL NANOPARTICLES, AND PRUSSIAN BLUE NANOPARTICLES THEREFROM

摘要

A new process for the preparation of noble metal nanoparticles[(e.g. gold nanoparticles (AuNPs), palladium nanoparticles (PdNPs]) and Prussian blue nanoparticles (PBNPs) is reported having the following components: (a) transition metal salt solution, (b) hydrophilic poly amine-functionalized organic reagent , (c) organic reducing agent, (d) HCl, (e) suitable noble metal salt solution, and the said process comprising (i) mixing transition metal salt solution (a) with hydrophilic poly amine- functionalized organic reagent (B) and adding organic reducing agent (c) and HCl (d) to obtain PBNPs suspension, (ii) mixing hydrophilic poly amine- functionalized organic reagent (b) and noble metal salt solution (e) followed by adding organic reducing agent (c) followed by mixing over vertex mixture to obtain respective noble metal nanoparticles suspension.
