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 TiO2 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.
