Photocatalytic Degradation of Methylene Blue Using TiO2/Carbon Nanoparticles Fabricated by Electrical Arc Discharge in Liquid Medium

Herein we modified TiO₂ anatase with carbon material using an electrical arc discharge technique in liquid medium to produce a nanoparticle of TiO₂/Carbon photocatalyst. The electrical arc discharge was performed using two graphite electrodes submerged in TiO₂ suspended in ethanol by passing electrical 20-40 V (10-50 A). X-ray Diffraction (XRD) peak profile analysis shows the successful modification confirmed from the presenting peaks which represent to crystalline TiO₂ and carbon element. The fabrication was then followed by the assessment of photocatalytic activity of fabricated nanoparticles in methylebe blue degradation under mercury lamp irradiation. After 60 minutes irradiation, the photocatalytic activity of TiO₂/Carbon increased more than three times higher compared to the photocatalytic activity of pristine TiO₂.
