 In this study, researchers investigated the effect of different reducing agents on the production of silver nanoparticles during sonochemical synthesis. They found that the optimal concentration of reducing agent varied depending on the type of reducing agent used, with more hydrophobic reducing agents requiring lower concentrations than less hydrophobic ones. Additionally, the presence of pyrolytic decomposition products increased the rate of reaction and reduced the required concentration of reducing agent.
