Commercial anatase TiO 2 powders (Tayca TKP101, TKP102) were ground with thiourea and annealed at 400 and 500 °C. Diffuse reflectance spectra (DRS) showed that the doping with thiourea shifted the TiO 2 absorption towards the visible region. The abs

Parylene films loaded with TiO2 are reported as hotocatalysts in azo dye discoloration processes. The TiO2 loading of the parylene film was 0.32% (w/w) and the amount of TiO2 on the film was about two orders of magnitude below the TiO2 added in suspe

This study presents the synthesis and activity of ZnSO4–TiO2 coated Raschig rings (RR). The activity of the Zn-doped catalyst (from now on Zn–TiO2/RR) was found to be higher than of the pure Degussa P25 TiO2 during the photodegradation of organic

Polyoxyethylated alkanols (CnEm) and nonylphenols (C9PhEm), or generally hydrocarbon polyethylene glycol ethers (REm), are preferentially adsorbed on solids with pHpzc lower than 4. This is due to basic character of OH groups of REm and acidic proper
