Quantum Efficiencies of the Photo-fenton Degradation of Atrazine in Water
(Iwa Publishing, 2012-10)
An experimental work in a well-stirred batch recycling reactor for the photo-Fenton degradation of atrazine in water is presented. A study of the quantum efficiency is performed to assess the effectiveness of the photo-Fenton ...

Insights on the structural and electrical transport of sodium titanate nanotubes decorated with CuInS2 quantum dots heterostructure
(Elsevier, 2021)
In this work we present the synthesis of nanoscale heterostructures comprising sodium titanate nanotubes
Na2Ti2O5·H2O (NaNT) decorated with CuInS2 (CIS) quantum dots with different sizes and weight fractions. Our
study ...
Performance in a fluidized bed reactor of photocatalysts immobilized onto inert supports
(Elsevier Science, 2000-05)
The performance of amodel photocatalyst (Degussa P25), immobilized onto quartz sand using a dry/wet physical deposition method has been studied in a fluidized-bed reactor. A simple model substrate, dilute oxalic acid, was ...
Acetaldehyde degradation under UV and Visible irradiation using CeO2-TiO2 composite systems: Evaluation of the photocatalytic efficiencies
(Elsevier, 2014-06)
The photocatalytic activity under UV and visible irradiation of a series of CeO2-TiO2 composite materials prepared by microemulsion and subsequently calcined at 500 0C was evaluated using acetaldehyde as a model pollutant. ...
Effect of different synthesis methods on the morphology, optical behavior, and superior photocatalytic performances of Ag3PO4 sub-microcrystals using white-light-emitting diodes
(Elsevier B.V., 2019-05-15)
In this paper, we report on the superior photocatalytic properties of silver orthophosphate (Ag3PO4) sub-microcrystals prepared using different synthesis methods: precipitation (PM), precipitation-calcination (PM-C), and ...
Radiation extinction of slurried TiO2 as a function of mechanical action and ionic composition of the suspending media: A key factor in the photocatalytic efficiency
(Elsevier Science, 2002-05)
Water contaminants can be completely mineralized by UV activated powdered TiO2. By recirculating slurried titania through a fluidized bed (FB) of quartz sand, the apparent quantum efficiency of the photocatalyst can be ...
Photochemical heat-shock response in common bean leaves as affected by previous water deficit
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2008)
The heat sensitivity of photochemical processes was evaluated in the common bean (Phaseolus vulgaris) cultivars A222, A320, and Carioca grown under well-watered conditions during the entire plant cycle (control treatment) ...
