Electrogeneration of hydrogen peroxide in gas diffusion electrodes modified with tert-butyl-anthraquinone on carbon black support
Ricardo Bertholo Valim,Rafael M. Reis,Pollyana S. Castro,Alex S. Lima,Robson S. Rocha,Mauro Bertotti,Marcos R.V. Lanza +6 more
TL;DR: In this paper, a modified gas diffusion electrode (MGDE) was applied to carbon black to generate hydrogen peroxide (H2O2) in the form of a microporous layer.
Journal ArticleDOI
Electrochemical synthesis of hydrogen peroxide on oxygen-fed graphite/PTFE electrodes modified by 2-ethylanthraquinone
TL;DR: In this article, the performance of a catalyzed H2O2 electrogeneration process using a modified oxygen-fed graphite/PTFE electrodes in which the redox catalyst was incorporated into the graphitic mass was investigated.
Journal ArticleDOI

TL;DR: In this paper, a comparative study using different proportions of CeO 2 /C (4, 9% and 13% ) was performed to produce H 2 O 2, a reagent used in the oxidation of organic pollutants and in electro-Fenton reactions for the production of the hydroxyl radical (OH ), a strong oxidant agent used in electrochemical treatment of aqueous wastewater.
Journal ArticleDOI
Electrogeneration of hydrogen peroxide in acidic medium using gas diffusion electrodes modified with cobalt (II) phthalocyanine
TL;DR: In this paper, the development of catalysts for the electrogeneration of H 2 O 2 in acidic medium using gas diffusion electrodes (GDE) was described, and initial experiments were performed using rotating ring-disk electrodes modified with microporous layers of Printex 6L carbon containing various amounts of cobalt (II) phthalocyanine (CoPc) in order to evaluate catalytic activities.
