A mechanistic study on photocatalysis by thiapyrylium salts. Photodegradationof dimethoate, alachlor and pyrimethanil under simulated sunlight

Gomis Vicens, Juan; Arques Sanz, Antonio; Amat Payá, Ana María; Marín García, Mª Luisa; Miranda Alonso, Miguel Ángel (Elsevier, 2012-07-23)

Photodegradation of dimethoate, alachlor, and pyrimethanil using a thiapyrilium salt (TPTP+) as photocatalyst was performed under simulated sunlight. The photocatalyst removes preferentially pyrimethanil (45% after 60 min ...
A photophysical approach to investigate the photooxidation mechanism of pesticides: Hydroxyl radical versus electron transfer

Marín García, Mª Luisa; Lhiaubet, Virginie Lyria; Santos-Juanes Jordá, Lucas; Soler Escoda, Juan Miguel; Gomis Vicens, Juan; Arques Sanz, Antonio; Amat Payá, Ana María; Miranda Alonso, Miguel Ángel (Elsevier, 2011-03-14)

[EN] The role of hydroxyl radical in different solar photocatalytic processes, namely photo-Fenton, titanium dioxide-based oxidation and organic photocatalysis (triphenylpyrylium) has been investigated. Using a methodology ...
Application of soluble bio-organic substances (SBO) as photocatalysts for wastewater treatment: Sensitizing effect and photo-Fenton-like process

Gomis Vicens, Juan; Vercher Pérez, Rosa Francisca; Amat Payá, Ana María; Martire, D. O.; Gonzalez, M. C.; Prevot, A. B.; Montoneri, E.; Arques Sanz, Antonio; Carlos, L. (Elsevier, 2013-06)

Soluble bio-organic substances (SBO) isolated from urban biorefuses have been investigated in photocatalytic processes for wastewater treatment using a cationic dye, namely crystal violet (CV) as target compound. The SBO ...
Bio-based substances from urban waste as auxiliaries for solar photo-Fenton treatment under mild conditions: Optimization of operational variables

Gomis Vicens, Juan; Carlos, L.; Bianco Prevot, Alessandra; Teixeira, A. C. S. C.; Mora Carbonell, Margarita; Amat Payá, Ana María; Vicente Candela, Rafael; Arques Sanz, Antonio (Elsevier, 2015-02-01)

The use of soluble bio-based organic substances (SBO) obtained from urban wastes to expand the pH region where the photo-Fenton process can be applied has been investigated in this study. For this purpose, a mixture of six ...
Direct detection of the triphenylpyrylium-derived short-lived intermediates in the photocatalyzed degradation of acetaminophen, acetamiprid, caffeine and carbamazepine

Martínez-Haya, Rebeca; Gomis Vicens, Juan; Arqués Sanz, Antonio; Amat Payá, Ana María; Miranda Alonso, Miguel Ángel; Marín García, Mª Luisa (Elsevier, 2018-08-15)

[EN] Advanced oxidation processes are useful methodologies to accomplish abatement of contaminants; however, elucidation of the reaction mechanisms is hampered by the difficult detection of the short-lived primary key ...

Efecto de distintas especies reactivas generadas fotoquímicamente sobre la eliminación de contaminantes presentes en aguas naturales

Gomis Vicens, Juan (Universitat Politècnica de València, 2015-06-15)

[EN] In this Doctoral Thesis the reactivity of a group of emerging pollutants (EP) present in the output waters of urban treatment plants and the implementation of a photo-Fenton process in slightly acidic pH conditions ...
Hydroxyl radical as an unlikely key intermediate in the photodegradation of emerging pollutants

Rodríguez Muñiz, Gemma María; Gomis Vicens, Juan; Arques Sanz, Antonio; Amat Payá, Ana María; Marín García, Mª Luisa; Miranda Alonso, Miguel Ángel (Wiley-Blackwell, 2014-11)

In this work, a kinetic model, in combination with time-resolved experiments, is applied to assess the involvement of OH in the photodegradation of emerging pollutants (EPs) by means of advanced oxidation processes. In ...
Time-resolved kinetic assessment of the role of singlet and triplet excited states in the photocatalytic treatment of pollutants at different concentrations

Martínez-Haya, Rebeca; Gomis, J.; Arques Sanz, Antonio; Marín García, Mª Luisa; Amat Payá, Ana María; Miranda Alonso, Miguel Ángel (Elsevier, 2017)

[EN] A kinetic-based rationale to assess the role of each excited species in thermodynamically favoured photocatalytic processes at different pollutant concentrations, has been developed and illustrated with new experimental ...
