Experimental and theoretical study of the electrochemical synthesis of silver nanoparticles using ampicillin as a stabilizing reagent

摘要

Electrochemical synthesis of silver nanoparticles on the surface of glassy carbon electrode using ampicillin as a stabilizing reagent are prepared. The silver nanoparticles are characterized by scanning electron microscopy, cyclic voltammetry, and infrared spectrometry. The electrochemical catalysis of AgNPs for sodium sulfide was demonstrated. The relationship between the molecular structure of ampicillin and the dispersion of GNPs on the surface of GCE as well as the catalysis of GNPs for sodium sulfide was discussed.
