UV or visible light induced photodegradation of AO7 on TiO2 particles: the influence of inorganic anions

Mechanism and experimental study on the photocatalytic performance of Ag/AgCl @ chiral TiO2 nanofibers photocatalyst: The impact of wastewater components

“…Therefore, it can be concluded that AgCl prevents Ag from reacting with inorganic ligands and thus stabilizes the Ag/AgCl system. However, the slight photocatalytic accelerations of NO 3 -and CO 3 2-were observed, due to their ability to generate HO· (photolysis of NO 3 -and CO 3 2-is an inevitable source of HO·) [31], while they did not induce any aggregation or dissolution.…”

Photocatalytic activity of Pt–TiO2 films supported on hydroxylated fly ash cenospheres under visible light

“…8. Because the common cation of all the added salts, Na + , is inert, only anions are involved in the photocatalytic reaction [41]. Fig.…”

Photolytic and thin TiO2 film assisted photocatalytic degradation of sulfamethazine in aqueous solution

“…As can be seen, the photocatalytic degradation of SMT is significantly slower in SWW than in Milli-Q water, with almost ninefold reduction in the photocatalytic degradation rate constant (k= 0.089 min −1 in SWW). The inhibition of SMT degradation can be attributed to the effects of different water constituents on the photodegradation (Guillard et al 2003;Wang et al 2004;Lair et al 2008). On the basis of the UV spectra of SWW constituents (citric acid, ascorbic acid, and saccharose), only the citric acid could impact the photolysis-decreasing photodegradation rate of SMT because it absorbs UV-C radiation (λ max at 264 and 261 nm) in the close wavelength range as the UV-C lamp.…”
