Abstract

Ag nanoparticles were synthesized through solution-phase chemical reduction of AgNO₃ via microwave irradiation. Polyacrylic acid (PAA) and polyvinyl pyrrolidone (PVP) were used as capping agents with water and ethanol as solvents, and sodium citrate, ethylene glycol, and NaBH_4. The microwave heating time, microwave heating power, AgNO₃ concentration, reducing agent concentration, capping agent concentration, and molar ratio of reducing agent to Ag nitrate, were optimized in cases where Ag nanoparticles were successfully synthesized. The use of PAA and sodium borohydride (NaBH₄) with water as solvent led to the synthesis of spherical Ag nanoparticles in the range of about 10-100 nm. The Ag nanoparticles produced were characterized using scanning electron microscopy (SEM) and UV-VIS spectrophotometry.
