Abstract

This study proposes a low-pressure control method for an arc-submerged nanoparticle synthesis system (ASNSS) developed for TiO₂ nanoparticle fabrication. The photocatalytic and surface adsorptive activity of TiO ₂ nanofluid is examined via the decomposition of methylene blue. Experimental results show that the ASNSS can successfully prepare anatase TiO₂. The rate constant of photocatalytic reaction of TiO₂ nanoparticles for methylene blue is 0.0365 (min^-1), and the rate constant of surface adsorption of methylene blue on TiO₂ is 0.0437 (min^-1). Experimental results indicate that the TiO₂ nanofluid prepared by the ASNSS has excellent photocatalytic activity and surface adsorption property for degradation of methylene blue.
