Rapid Synthesis of Metal-doped Nano-sized Particles for Photocatalyst by Photo-ionization－Flame Method

Abstract

An aerosol tubular reactor system to synthesize nanostructured vanadium doped titanium dioxide particles is described. The resultant particle size distributions, crystal phases, and morphology and distribution of dopant are established as a function of the operating conditions. The addition of the dopant promotes sintering and an increase in the primary particle size. Downstream of the furnace, a corona-soft X-ray reactor is used to demonstrate the effectiveness in degradation of toluene. An improvement in the degradation rates is observed when soft X-ray irradiation is used in conjunction with the corona. Addition of the V-dopant enhanced the photodegradation of toluene.
