Photocatalytic removal of VOCs on TiO2 nanotubular arrays: Modelling of mass transfer inside nanotubes
Original language description
The present study describes a mathematical model of the steady-state photocatalyticdegradation of volatile organic compounds (VOCs) on nanotubular TiO2 layers in aflow-through photoreactor. The experimental setup for gas phase photocatalysis wasdesigned according to the ISO standard (ISO 22197) with a photocatalyst surface areaof 50 cm2 and acetaldehyde as a model gaseous pollutant. To the best of ourknowledge, a comprehensive model explaining mass transfer inside TiO2 nanotubesduring the VOCs removal has been successfully developed and verified for the firsttime. The results of the model showed that the photocatalytic degradation of VOCs isnot limited by mass transfer inside the TiO2 nanotubes under the given conditions andthe process is controlled only by the kinetics of photocatalytic degradation. This modelhas the potential to change our approach to designing efficient photocatalytic systemsand optimizing the removal of hazardous air pollutants.
