- Abstract
This study proposes a new method: the combined arc-submerged nanoparticle synthesis system (ASNSS) for preparing TiO2 nanofluid. In addition to the influence of the various process variables such as breakdown voltage, peak current and dielectric liquid temperature on nanoparticles, this study will also discuss the photocatalytic activity of the prepared TiO2 nanoparticle suspension. To examine the photocatalytic activity of the TiO2, the photodecomposition of salicylic acid was carried out. Experimental results show that the proposed method can successfully prepare anatase TiO2 and this nanofluid can be stabilised for longer than six months. The rate constant of photocatalytic reaction of TiO2 nanoparticles for salicylic acid is 0·0035. Experimental results indicate that the TiO2 nanoparticle fluid possesses excellent photocatalytic activity in photodegradation of salicylic acid.
