Electrochemical formation of silver nanoparticles and their catalytic activity immobilised in a hydrogel matrix

Silver nanoparticles were formed electrochemically in the presence of poly( N -vinylpyrrolidone) (PVP) to generate highly stable nanoparticles with a mean diameter of 12 nm. The optimised conditions involved formation at − 6.0 V vs Ag|Ag + with a PVP:Ag + ratio of 75:1. Particle agglomeration was ob...
