Advanced materials are needed to meet the requirements of devices designed for harvesting and storing renewable electricity. In particular, polymer electrolyte membrane water electrolyzers (PEMWEs) could benefit from a reduction in size iridium oxide (IrOx) particles used electrocatalyze sluggish oxygen evolution reaction (OER). To verify validity this approach, we built library 18 supported unsupported IrOx catalysts established their stability number (S-number) values using inductively...
Niobium and antimony doped tin oxide loose-tubes decorated with Pt nanoparticles present outstanding mass activity stability, exceeding those of a reference carbon-based electrocatalyst. Physico-chemical characterisation in particular X-ray photoelectron spectroscopy demonstrate that this observation can be ascribed to the strong metal-support interaction promoting electroactivity anchoring on metal supports.
Electrocatalyst supports stable to high potential are required for the proton exchange membrane fuel cell cathode. based on tantalum-doped tin oxide (Ta/SnO2) were prepared by electrospinning. The dopant amount was varied between 0 (undoped SnO2) and 7.5 at. %, resulting materials characterized their morphology, composition, structure, porosity, electrical properties. Platinum nanoparticles a microwave-assisted polyol method deposited with different loadings 1 % Ta-doped SnO2 (1Ta/SnO2),...
Abstract In this paper, an extensive characterisation of a range carbon blacks (CB) with similar surface area but different chemistry is carried out by flow calorimetry, Raman spectroscopy, dynamic water vapour sorption, instrumental gas analysis, nitrogen adsorption/desorption and high potential chronoamperometry. Using these materials as supports, Pt/CB electrocatalysts are prepared microwave‐assisted polyol‐mediated synthesis in gram scale. Structural, morphological electrochemical...
Cobalt hexacyanoferrate on Sb-doped SnO<sub>2</sub>as a non-noble catalyst for O<sub>2</sub>evolution in acidic medium.
The systematic study of the impact treatment temperature IrOx supported onto doped-tin oxide (1 at.% Ta-SnO2 and 10 Sb-SnO2) fibres led to electrocatalysts with high activity...
Abstract High durability and activity for the oxygen reduction reaction were demonstrated oxide‐supported platinum catalysts. The supports antimony‐doped SnO 2 (ATO) fibres‐in‐tubes obtained by electrospinning subsequent calcination. doping with antimony instead of already‐reported niobium, allowed preparation tin oxide electrical conductivity that was similar to carbon, which also had an increased electrocatalyst loading. Platinum nanoparticles supported on electrospun ATO higher...
In this study, the resistance to corrosion of niobium-doped tin dioxide (Nb-doped SnO2, NTO) and antimony-doped oxide (Sb-doped ATO) supports has been probed for proton-exchange membrane fuel cell (PEMFC) application. To achieve goal, ATO or NTO with loose-tube (fiber-in-tube) morphology were synthesized using electrospinning decorated platinum (Pt) nanoparticles. These cathode catalysts submitted two different electrochemical tests, an accelerated stress test following EU Harmonised Test...
Abstract Three protonated zeolites (H‐ZSM‐5, H‐Y and H‐Beta) were prepared tested in the catalytic dehydration of glucose into 5‐hydroxymethylfurfural (HMF). The results are compared with those obtained a mesoporous MCM‐41‐type aluminosilicate, order to assess influence textural acid properties on performance. process was carried out biphasic water/methyl‐isobutyl ketone (MIBK) system, positive effect NaCl addition (20 wt. %) both HMF selectivity yield observed. Using H‐Beta zeolite aqueous...

SBA-15 type ordered silicas possessing amino groups attached onto their surfaces were prepared by using two different functionalization methodologies. These matrices used for the cephalexin adsorption from aqueous solution and further kinetic study of its release into physiological solution. The materials characterized nitrogen adsorption/ desorption, scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), X-Ray photoelectron spectrometry (XPS) thermo analytical...
