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 ...
One-step hydrothermal synthesis and photocatalytic performance of ZnWO4/Bi2WO6 composite photocatalysts for efficient degradation of acetaldehyde under UV light irradiation
(Elsevier Science Bv, 2013-04)
Bi2WO6 with different Bi3+ ion concentrations (0?30 mol%) is incorporated with the ZnWO4 photocatalyst to improve the photocatalytic efficiency by forming a ZnWO4/Bi2WO6 composite photocatalyst with hierarchical heterostructure ...
Composites of laminar nanostructured ZnO and VOx - Nanotubes Hybrid as visible light active photocatalysts
(MDPI, 2018)
A series of hybrid heterostructured nanocomposites of ZnO with V2O5 nanotubes (VOx-NTs) in different mixing ratios were synthesized, with the aim of reducing the recombination of photoinduced charge carriers and to optimize ...
Carbon dots from agroindustrial residues: a critical comparison of the effect of physicochemical properties on their performance as photocatalyst and emulsion stabilizer
(Elsevier, 2021-06)
Carbon dots have been synthesized through a pyrolysis route with agroindustrial wastes of Yerba Mate (YM), Avocado Seed (AS), and Orange Peel (OP) as raw materials. The selection of the pyrolysis temperature was according ...

(2016-07-15)
Photocatalytic water treatment has a currently elevated electricity demand and maintenance costs, but the photocatalytic water treatment may also assist in overcoming the limitations and drawbacks of conventional water ...
Photocatalytic activity of TiO2 films prepared by cathodic arc deposition: Dependence on thickness and reuse of the photocatalysts
(Elsevier Science SA, 2019-11)
In this work, the photocatalytic activity of anatase films with thicknesses up to 1100 nm prepared by cathodic arc deposition (CAD) on glass substrates is reported. The photocatalytic activity under UV–Vis irradiation (λ ...
Prussian blue as a co-catalyst for enhanced Cr(vi) photocatalytic reduction promoted by titania-based nanoparticles and aerogels
(Royal Soc Chemistry, 2021-04-26)
Hexavalent chromium (Cr(vi)) is an noxious and highly toxic heavy metal that presents a serious threat to human health if present even in low concentrations in drinking water. Photocatalytic reduction of Cr(vi) to its less ...
