Flower-like WO3-modified Vulcan carbon GDEs for photoelectro-Fenton process: Efficient ciprofloxacin degradation and mechanistic insights
João Paulo C. Moura, Vanessa S. Antonin, Caio Machado Fernandes +8
Electrochemical H2O2 synthesis was investigated using a 3 percent WO3 C gas diffusion electrode GDE. The catalyst outperformed bare Vulcan carbon, generating H2O2 concentrations of…
Resilience of the physicochemical properties of graphene-based materials for applications in harsh radiation environments
Marcilei A. Guazzelli, Saulo G. Alberton, Nemitala Added +16
The development of radiation-tolerant materials capable of maintaining structural, electrical, and thermal stability in extreme, radiation-rich environments remains a critical chal…
Oxophilic Silver-Based Nanoparticles with Low Pd-Au Loading for Ethanol and Glycerol Electrooxidation in Alkaline Media
Tuani Carla Gentil, Camilo Andrea Angelucci, Bruno Lemos Batista +5
The electrocatalytic activity of oxophilic Ag nanoparticles, combined with small amounts of Pd and Au, was investigated for ethanol oxidation reactions (EOR) and glycerol oxidation…
Stability of Supported Pd-based Ethanol Oxidation Reaction Electrocatalysts in Alkaline Media
Tuani C. Gentil, Maria Minichova, Valentín Briega-Martos +7
This study evaluates the dissolution of the supported electrocatalysts Pd/C, PdSn/C, PdNb/C, and PdFe3O4/C during ethanol oxidation reaction for ADLFC applications. A scanning flow…
Fe3O4 nano-octahedra and SnO2 nanorods modifying low-Pd amount electrocatalysts for alkaline direct ethanol fuel cells
Tuani C. Gentil, Lanna E. B. Lucchetti, João Paulo C. Moura +7
This work describes the ethanol oxidation reaction (EOR) in alkaline medium using low-palladium nanoparticle electrocatalysts modified by Fe3O4 nano-octahedra and SnO2 nanorods. Op…
Photo-Assisted Pd-Nb2O5/Carbon Nanocomposites for Enhanced Ethanol Electro-Oxidation Kinetics and CO Tolerance in Alkaline Media
João V. T. Neves, Stephanie S. Aristides-Barros, Aline B. Trench +4
Pd-based anodes for alcohol oxidation suffer from surface poisoning and sluggish kinetics. Here, we developed Pd-Nb2O5/C nanocomposites to improve ethanol electrooxidation kinetics…
