Optimal Conditions Linked to the Reducing Agent on the Role of Morphology of Silver Nanoparticles

Abstract This study optimizes silver nanoparticle synthesis using response surface methodology to predict particle size diameter. Factors including agitation frequency, flow, temperature, reducing agent concentration, and heating time were varied using citrate and borohydride separately. Particle size was measured via dynamic light scattering and morphology analyzed by transmission electron microscope. Regardless of the reducing agent, concentration most significantly influenced particle size. Interactions were also crucial. Sodium borohydride synthesis yielded small, narrowly distributed nanoparticles across various size ranges. The study demonstrates the production of nanometric particles suitable for diverse technological applications.
