Advances in Photocatalytic Organic Synthetic Transformations in Water and Aqueous Media
(American Chemical Society, 2021-07)
Advances in visible light-photocatalyzed preparative synthetic organic transformations in water or aqueous media are studied. Both the convenience of visible light photocatalytic strategies to achieve synthetic organic ...
Mechanisms of removal of heavy metals and arsenic from water by TiO2-heterogeneous photocatalysis
(De Gruyter, 2015-06)
This article is an overview of recent work performed in our laboratory on TiO2 heterogeneous photocatalysis of aqueous systems containing toxic forms of chromium, arsenic, lead, uranium and mercury. The cases of chromium ...
Braiding kinetics and spectroscopy in photo-catalysis: the spectro-kinetic approach
(Royal Society of Chemistry, 2019-01)
The combination of kinetic and spectroscopic tools has become a key scientific methodology for the understanding of catalytic behavior but its application in photocatalysis has inherent difficulties due to the nature of ...
Simultaneous detection and photocatalysis performed on a 3D graphene/ZnO hybrid platform
(American Chemical Society, 2020-02-12)
The synergy between graphene foam (Gf) and ZnO nanoparticles (NPs) allows the detection of analytes at low conentrations, which can be subsequently photocatalyzed on the hybrid surface as well as in the liquid phase upon ...
Nitric oxide emission during the reductive heterogeneous photocatalysis of aqueous nitrate with TiO2
(Royal Society of Chemistry, 2015-10)
For the first time, nitric oxide (NO), a precursor of nitrogen dioxide (NO2, a NIOSH-listed atmospheric pollutant), has been found to be one of the final products of the photocatalytic reduction of nitrate in water using ...
Treatment of ethylmercury chloride by heterogeneous photocatalysis with TiO2
(Elsevier Science SA, 2021-04)
Ethylmercury chloride (C2H5HgCl) was treated by UV/TiO2 photocatalysis in the presence of O2 and under N2 at pH 4.2. No report exists on C2H5Hg+ degradation by heterogeneous photocatalysis. The adsorption of C2H5Hg+ over ...
Biological degradation coupled to photocatalysis by ZnO/polypyrrole composite for the treatment of real textile wastewater
(Elsevier, 2020-06)
The novelty of this work lies in the use of a real textile wastewater (RTW), without a pretreatment, without additional carbon sources and undiluted, with coupling a photocatalysis by using an unprecedented composite for ...
Abatement of toxicity of effluents containing Cr(VI) by heterogeneous photocatalysis. Toxicity assessment by AMPHITOX assay
(Academic Press Inc Elsevier Science, 2015-09)
Toxicity of a Cr(VI) solution before and after treatment by TiO2 heterogeneous photocatalysis (HP) was performed with AMPHITOX bioassay. Changes in toxicity on Rhinella arenarum larvae for 10-d were monitored after exposure ...
Angle dependence in slow photon photocatalysis using TiO2 inverse opals
(Elsevier Science, 2018-03)
The slow photon effect was studied by means of the photocatalytic degradation of stearic acid over TiO2 inverse opals. The comparison of the degradation rates over inverse opals with those obtained over disordered structures ...
