Enhanced Photocatalytic Degradation of the Imidazolinone Herbicide Imazapyr upon UV/Vis Irradiation in the Presence of CaᵪMnOᵧ-TiO₂ Hetero-Nanostructures: Degradation Pathways and Reaction Intermediates
(MDPI, 2020-05-08)
[Abstract] The determination of reaction pathways and identification of products of pollutants degradation is central to photocatalytic environmental remediation. This work focuses on the photocatalytic degradation of the ...
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% ...
A Snapshot on the Occurrence and Risk Assessment of Organic Pollutants in an Urban River
(MDPI, 2022-12-22)
[Abstract] A snapshot screening was carried out in an urban river at the end of a dry period in the water and sediments to assess the presence and environmental risk for the following CECs: paracetamol, ibuprofen, diclofenac, ...
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, ...
Combining Constructed Wetlands and UV Photolysis for the Advanced Removal of Organic Matter, Nitrogen, and Emerging Pollutants from Wastewater
(MDPI, 2023-02-23)
[Abstract] This study reports the performance of a three-step lab-scale system including a hybrid digester (HD), a vertical flow (VF) constructed wetland, and a photodegradation (PD) lamp, with two different arrangements ...
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 ...
Removal of Emerging Pollutants by a 3-Step System: Hybrid Digester, Vertical Flow Constructed Wetland and Photodegradation Post-treatments
(Elsevier, 2022-06-22)
[Abstract] The removal of emerging pollutants from municipal wastewater was studied for the first time using a three-step pilot-scale system: 1) hybrid digester (HD) as first step, 2) subsurface vertical flow constructed ...
