The guest editor introduces a selection of papers presented at the 10th European Meeting on Solar Chemistry & Photocatalysis: Environmental Applications – SPEA10.
Intensification of the O3/TiO2/UV advanced oxidation process using a modified flotation cell
A novel approach for the ozone and TiO2 intensification process for wastewater treatment is presented using a modified flotation cell.
Photo-oxidative and photo-reductive capabilities of ilmenite-rich black sand concentrates using methyl orange as a probe molecule
Ilmenite-rich black sand concentrates exhibited potential photo-oxidative and, especially, photo-reductive capabilities which were affected by sample purity and color.
Paper
Visible-light activation of TiO2 by dye-sensitization for degradation of pharmaceutical compounds
A kinetic model for the dye sensitization process of TiO2 that considered photon absorption was developed.
A new automated solar disc for water disinfection by pasteurization
A new automated Solar Water Pasteurization Disc of double reflection of 3.8 and 1.3 m in diameter for the first and second reflectors has been erected and tested for performing microbiological disinfection of water in a simple, efficient, and continuous treatment in Brazil.
Disinfection performance using a UV/persulfate system: effects derived from different aqueous matrices
The disinfectant power of UV combined with a persulfate salt has been assessed. The results obtained suggest this system as an attractive alternative to other photochemical processes currently in use for seawater treatment.
Transparent rutile TiO2 films prepared by thermal oxidation of sputtered Ti on FTO glass
Compact and photoactive transparent rutile TiO2 films were deposited by a two-step process: (i) magnetron sputtering of Ti films on a heated FTO substrate and (ii) subsequent thermal oxidation.
Photocatalytic inactivation of bioaerosols in a fixed-bed reactor with TiO2-coated glass rings
The photocatalytic inactivation of Bacillus subtilis spores in air was evaluated employing a fixed-bed reactor with TiO2-coated glass rings, under artificial UV-A radiation.
Ta3N5/Co(OH)x composites as photocatalysts for photoelectrochemical water splitting
Elaboration of the stability issue related to the morphology of nanotubes, and enhancement of the PEC stability by loading double co-catalysts.
Synthesis of Cd1−xZnxS photocatalysts for gas-phase CO2 reduction under visible light
Gas-phase CO2 reduction with H2O on Cd1−xZnxS-based photocatalysts has been performed for the first time.
Automated on-line monitoring of the TiO2-based photocatalytic degradation of dimethyl phthalate and diethyl phthalate
An automated on-line system for monitoring the TiO2-based photocatalytic degradation of dimethyl phthalate and diethyl phthalate.
Photocatalytic abatement of emerging pollutants in pure water and wastewater effluent by TiO2 and Ce-ZnO: degradation kinetics and assessment of transformation products
A good removal efficiency was obtained for a mixture of seven emerging contaminants in wastewater effluent using two catalysts, Ce-ZnO and TiO2-SG, as evidenced by the formation of several transient transformation products.
Anoxic photocatalytic treatment of synthetic mining wastewater using TiO2 and scavengers for complexed cyanide recovery
A new pathway for selective photocatalytic reduction using a combination of scavengers for gold mining wastewater treatment.
