In this study, an ultrasound-assisted spiral minireactor was used to synthesize Ag-doped Fe 3 O 4 nanoparticles. When compared to the traditional (without ultrasonic) method of producing nanoparticles, the use of a minireactor with ultrasonication provides a more effective method of producing nanoparticles. Effect of various molar ratios of AgNO 3 :NaBH 4 on the structure of synthesized Ag-doped Fe 3 O 4 nanoparticles was investigated. Formation of the nanocomposite was examined by UV, FTIR, TEM, and XRD. For comparison purpose, Ag-doped Fe 3 O 4 nanoparticles were also prepared using the same procedure and reaction conditions without the use of ultrasound. There is no study that provides the protocol to synthesize nanocomposite material continuously. Moreover, a fast synthesis method for production of Ag-doped Fe 3 O 4 nanoparticles is not yet disclosed. It focuses on the optimization of AgNO 3 :NaBH 4 ratio for achieving desired nanocomposite material. Assistance of ultrasound to the minireactor is an efficient method for nanoparticles production. This is due to the effective contact of reactants, exposure of Fe 3 O 4 surface area, distribution of Ag nanoparticles over Fe 3 O 4 surface, and particle size reduction. Thus, this method is proved to be eligible for scaling up for large-scale production of different types of nanoparticles.
