Enhancement of high temperature PEMFC stability using catalysts based on Pt supported on SiC based materials

“…These peaks correspond to the fcc cubic structure. As it can be observed, both materials show similar diffraction peaks [19]. However, the main diffraction peak for SiC is at 35.5 • and for TiC is at 41.7 • which would explain the higher intensity of this peak in the SiCTiC sample.…”

Composite Titanium Silicon Carbide as a Promising Catalyst Support for High‐Temperature Proton‐Exchange Membrane Fuel Cell Electrodes

“…These peaks correspond to the face‐centered cubic (fcc) structure. As can be observed, both materials show similar diffraction peaks, which it makes difficult to distinguish them . However, the main diffraction peak for SiC is at 35.6° and for TiC it is at 41.7°.…”

β-SiC alveolar foams as a structured photocatalytic support for the gas phase photocatalytic degradation of methylethylketone

“…Alveolar open-cell self-bonded ␤-SiC foams with medium specific surface area were synthesized by the SICAT Company (Willstätt, Germany) according to the shape memory synthesis (SMS) replica method, in which a pre-shaped polyurethane foam is transformed into the corresponding ␤-SiC carbide [27]. This method is a four step synthesis process, consisting in (i) the impregnation/infiltration of a pre-shaped precursor polyurethane foam with a phenolic resin containing micronized metallic silicon (<20 m), (ii) a polymerization step at 150-250 • C, (iii) a reactive step at 1360 • C under argon, with the attack of carbon by SiO vapors formed by reaction between the silicon and the resin oxygenated compounds, to yield ␤-SiC, and (iv) a final thermal treatment in air at 700 • C for removing residual unreacted carbon by combustion.…”

“…These properties also allow (if necessary) the easy regeneration of possibly deactivated supported photocatalysts to be performed without any irreversible damages, by thermal or soda-washing treatment. In addition, binder-free foams composed of self-bonded ␤-SiC grains can be easily manufactured with on-demand shapes for meeting the photoreactor geometry requirements through the implementation of the shape memory synthesis (SMS) replica method [27]. They also take advantage from a medium specific surface area for dispersing photocatalysts and from a high density of oxygenated surface groups for anchoring TiO 2 [28][29][30].…”
