An Ultrasound-Assisted Minireactor System for Continuous Production of TiO₂ Nanoparticles in a Water-in-Oil Emulsion

In this work, ultrasound-assisted synthesis of TiO2 nanoparticles in a water-in-oil emulsion in a minireactor has been introduced. For this, a lab-scale ultrasound-assisted minireactor system was developed. Experiments were carried out at different precursor solution flow rates, precursor and surfactant concentrations, and minireactor geometries. Lowering the precursor concentration and flow rate significantly decreases the average particle size...
