Photocatalytic degradation of indole in a circulating upflow reactor by UV/TiO2 process—Influence of some operating parameters

Photocatalytic oxidation of organic dyes and pollutants in wastewater using different modified titanium dioxides: A comparative review

“…In a system degrading indole, an increase in flow rate from 0.5 to 4.03 mL/s, led to a decrease of the indole degradation from 93% to 58% which was resulted from affecting the adsorption on the surface of TiO 2 and the photocatalytic reaction [88]. It also influences agglomeration of catalyst particles in the case of non supported media.…”

Laboratory and Pilot-Plant Scale Photocatalytic Degradation of Polychlorinated Biphenyls in Seawater Using CM-n-TiO2Nanoparticles

“…Further increase in the catalyst loading leads to the reduction of the degradation rate, revealing optimum catalyst loading of 0.5 g/L. The observed decrease in degradation rate can be attributed to the agglomeration of catalyst particles in addition to the light shading by the suspension [18,19].…”

Simultaneous Hydrogen Production with the Degradation of Naphthalene in Seawater Using Solar Light-Responsive Carbon-Modified (CM)-n-TiO<sub>2</sub> Photocatalyst

“…Additionally, the increase of the turbidity of the suspension reduces light penetration due to the enhancement of light scattering; the result is the decrease of the number of activated sites on the TiO 2 surface and shrinking of the effective photoactivated volume of suspension. The interplay of these two processes resulted in a reduced performance of photocatalytic activity with the overloaded catalyst [34,35]. In this study, the dosage of 1.0 g·L −1 of CM-n-TiO 2 can be considered as the optimal catalyst loading.…”
