Improved Photocatalyzed Degradation of Phenol, as a Model Pollutant, over Metal-Impregnated Nanosized TiO₂
(MDPI, 2020-05-22)
[Abstract] Photocatalyzed degradation of phenol in aqueous solution over surface impregnated TiO₂ (M = Cu, Cr, V) under UV-Vis (366 nm) and UV (254 nm) irradiation is described. Nanosized photocatalyts were prepared from ...
Preparation, Characterization and Testing of a Bulky Non-supported Photocatalyst for Water Pollution Abatement
(Elsevier, 2023-03-15)
[Abstract] An innovative bulky photocatalyst for water decontamination has been developed. The semiconductor (TiO2) is homogeneously distributed in an aggregating material through the whole piece. This design prevents the ...
Face-Fusion of Icosahedral Boron Hydride Increases Affinity to γ‐Cyclodextrin: closo,closo‐[B₂₁H₁₈]⁻ as an Anion with Very Low Free Energy of Dehydration
(Wiley, 2020-03-12)
[Abstract] The supramolecular recognition of closo,closo‐[B₂₁H₁₈]⁻ by cyclodextrins (CDs) has been studied in aqueous solution by isothermal titration calorimetry and nuclear magnetic resonance spectroscopy. These solution ...
An Efficient Green Photo-Fenton System for the Degradation of Organic Pollutants. Kinetics of Propranolol Removal From Different Water Matrices
(Elsevier, 2022-01-06)
[Abstract] We report on the degradation of aqueous propranolol (PRO) in a heterogeneous system with natural iron oxide (N.I.O.) and oxalic acid (OAA) under near UV–Vis irradiation. Photolysis experiments showed ca. 65% ...
Common Reactivity and Properties of Heme Peroxidases: A DFT Study of Their Origin
(MDPI, 2023-01-28)
[Abstract] Electronic structure calculations using the density-functional theory (DFT) have been performed to analyse the effect of water molecules and protonation on the heme group of peroxidases in different redox (ferric, ...
Effect of Ionizing Radiation on Human Myeloperoxidase: Reaction With Hydrated Electrons
(Elsevier, 2021-11-27)
[Abstract] Myeloperoxidase (MPO) is a myeloid-lineage restricted enzyme largely expressed in the azurophilic granules of neutrophils. It catalyses the formation of reactive oxygen species, mainly hypochlorous acid, ...
Cobalt Impregnation on Titania Photocatalysts Enhances Vis Phenol Photodegradation
(MDPI, 2023-06-01)
[Abstract] One of the main challenges of photocatalysis is to find a stable and effective photocatalyst, that is active and effective under sunlight. Here, we discuss the photocatalytic degradation of phenol as a model ...
Mechanical Stability Is Key for Large-Scale Implementation of Photocatalytic Surface-Attached Film Technologies in Water Treatment
(Frontiers, 2021-10-18)
[Abstract] Replacement of classical tertiary water treatment by chemical-free sunlight-driven photocatalytic units has been often proposed. Photocatalysts are required to be cost-effective, inert, chemically stable, reusable, ...
Inactivation of E. Coli and S. Aureus by Novel Binary Clay/Semiconductor Photocatalytic Macrocomposites Under UVA and Sunlight Irradiation
(Elsevier, 2023-09-08)
[Abstract] The disinfection efficiency of several novel photocatalytic macrocomposites made of Ecuadorian clay mixed with two semiconductor materials (TiO2, ZnO) has been evaluated with Staphylococcus aureus and Escherichia ...
Removal of Paracetamol in the Presence of Iron(III) Complexes of Glutamic and Lactic Acid in Aqueous Solution Under NUV Irradiation
(Elsevier, 2021-01-05)
[Abstract] Low concentrations of drugs and their metabolites occurring on the aquatic environment are of significant concern due to their potential effects. This work reports on the removal from aqueous solution, of ...
