A combined photolytic–electrolytic system for the simultaneous recovery of copper and degradation of phenol or 4-chlorophenol in mixed solutions [PDF]

open access: yes, 2008
The effects of the presence of copper on the photooxidation of phenol and 4-chlorophenol and of the presence of the phenols on the recovery of copper by electrodeposition are studied in three systems: a photolytic cell in the presence and absence of TiO2

Synthesis and characterization of silver vanadates thin films for photocatalytic applications [PDF]

open access: yes, 2017
Silver vanadates thin films were deposited by a hybrid deposition system combining laser ablation and thermal evaporation. A high purity vanadium target was ablated using the third harmonic of a Nd:YAG laser whereas high purity silver pellets were ...

THE INFLUENCES OF Fe(III) ION and Fe(OH)3 COLLOID ON THE PHOTODEGRADATION of p-CHLOROPHENOL CATALYZED BY TiO2

open access: yesIndonesian Journal of Chemistry, 2010
The influences of ionic Fe(III) and colloidal Fe(OH)3 on the effectiveness of p-chlorophenol photodegradation catalyzed by TiO2 has been studied. Photodegradation was carried out in a batch system by irradiating a suspension of TiO2, p-chlorophenol, and ...

Photochemical pathways of 8-oxo-2′-deoxyguanosine under photodegradation

open access: yesAIP Advances, 2022
The common product of an oxidatively damaged DNA, 8-oxo-2′-deoxyguanosine (8-oxo-dG), is known for photorepairing cyclobutane pyrimidine dimers. This study is to uncover the dynamics of 8-oxo-dG under photodegradation, which are poorly understood.

Photodegradation of glyphosate in water and stimulation of by-products on algae growth

open access: yesEcotoxicology and Environmental Safety, 2023
Glyphosate is the most widely used herbicide in global agricultural cultivation. However, little is known about the environmental risks associated with its migration and transformation. We conducted light irradiation experiments to study the dynamics and
