Abstract

This paper proposes a new method - the ultrasonic vibration-assisted arc-submerged nanoparticle synthesis system for preparing TiO2 nanoparticle preparation. In addition to the influence of the ultrasonic amplitude and various process variables such as breakdown voltage, pulse duration, current, and dielectric liquid temperature on particles, this paper will also discuss the relationship between the pH value and the surface potential of the suspension. Experimental results have shown that the proposed method can successfully prepare anatase type TiO2. The TEM image further shows a mean particle size below 10 nm, and that nanoparticle suspension cannot reach a state of stable suspension and starts aggregating under a pH value below 6.4.
