A sol-gel process followed by hydrothermal reaction was used to prepare coupled WO₃-TiO₂ photocatalysts with varying amounts of WO₃ in respect to TiO₂ (3 mol% and 5 mol% respectively). Additionally, photocatalysts have been subjected to different calcination temperatures of 400ºC and 800ºC, which allowed us to compare how these affect photodegradation efficiency. Photocatalysts were characterized...
Carbon dioxide and water vapor were effectively photoconverted to methane using either pure or modified-TiO2 and UV-Vis irradiation. The process of photoconversion in the gas phase was carried out in a tubular reactor equipped with a perforated TiO2-coated support. The effect of selected parameters of TiO2 immobilization procedure, such as the time and temperature of drying step and the photocatalyst...
The Cu-TiO2 and Ag/Cu-TiO2 nanoparticles have been prepared using a water-in-oil microemulsion system of water/AOT/cyclohexane. The photocatalytic activity of the catalysts was estimated by measuring the decomposition rate of phenol in 0.21 mM aqueous solution under visible light irradiation. The bioactivity of Ag/Cu-doped titanium (IV) oxide nanocomposites was estimated using bacteria Escherichia...
