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…
Influence of CeOMnO heterostructure on Hydrogen Peroxide Electrogeneration on Carbon-Based Catalysts
Caroline de O. Carrilho, Juliana M. S. de Jesus, João Paulo C. Moura +7
The sustainable electrogeneration of hydrogen peroxide (H2O2) via the two-electron oxygen reduction reaction (2e ORR) represents a promising alternative to conventional product…
Fe3O4 Nano-octahedra/Vulcan XC72: Optimization and Combination with Solar-Based Electro-Fenton for Progestins Degradation
Juliana M. S. de Jesus, Caroline de O. Carrilho, João P. C. Moura +4
The widespread presence of synthetic progestins, such as levonorgestrel (LNG) and gestodene (GES), in aquatic environments poses significant ecotoxicological risks due to their end…
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…
Effect of Fluorine doping on the electrocatalytic properties of Nb2O5 for H2O2 electrogeneration
Aline B. Trench, João Paulo C. Moura, Caio Machado Fernandes +1
The oxygen reduction reaction (ORR) via the 2-electron mechanism is an efficient way to produce hydrogen peroxide (H2O2) under mild conditions. This study examines the modification…
