Block copolymer mediated generation of bimetallic Ni-Pd nanoparticles: Raman sensors of ethyl paraben and ciprofloxacin
2018
Abstract In this research article, a highly simplified approach for the synthesis of nickel palladium bimetallic nanoparticles (Ni-PdNPs) is discussed. The synthesis method is of high novelty as it excludes involvement of any hazardous chemical and complicated laboratory set up. It is well known that generating a bimetallic nanoparticle involving nickel and palladium is a challenging task due to the difference in the reduction potential of the two metals E 0 (V vs. SHE) for Ni 2 + is − 0.25 V and Pd 2 + is 0.95 V respectively. One pot synthesis method of this material with a biocompatible polymer (PEG-PPG-PEG) which is mediated at room temperature is reported here for the first time. The synthesized particles are of size
