Photocatalytic degradation of volatile organics on TiO2 embedded glass spherules

Application of visible-light photocatalysis with nitrogen-doped or unmodified titanium dioxide for control of indoor-level volatile organic compounds

“…As such, since the distance of the catalyst from the light source increases when increasing the HD, the decrease in the light intensity in the reactor with a higher HD would seem to be the most obvious reason for the drop in the degradation of the target compounds. The effect of the light intensity is also supported by previous studies [40,41], which found that the oxidation rate of BTEX or trichloroethylene increased with an increase in the UV intensity. However, it is noteworthy that the quantum yield can decrease as the light intensity increases [40], and light intensity is one of the major parameters associated with the operation cost of photocatalytic systems [42].…”

Influence of fluorine on the structure and photocatalytic activity of TiO2 film prepared in tungstate-electrolyte via micro-arc oxidation

“…In general, the increase of specific surface area can enhance the photocatalytic activity of TiO 2 film effectively, which has been confirmed also by several other previous studies [18,19].…”

Synthesis, characterization, and photocatalytic application of novel TiO2 nanoparticles

“…Photocatalytic oxidation (PCO) of VOCs is a promising alternative technology for air purification. It has been demonstrated that organics can be oxidized to carbon dioxide, water and simple mineral acids at low temperature on TiO 2 catalysts in the presence of UV or near-UV illumination [10][11][12][13][14][15][16][17][18][19].…”
