Abstract:Résumé -La caractérisation par la méthode magnétique des catalyseurs Fischer-TropschCet article passe en revue les développements récents dans le domaine de la caractérisation des catalyseurs Fischer-Tropsch à base de cobalt, de fer et de nickel par la méthode magnétique. La caractérisation magnétique fournit des informations précieuses sur la réduction du catalyseur, la taille des nanoparticules ferromagnétiques, la chimisorption, ainsi que sur les réactions topochimiques qui se produisent avec les catalyseur… Show more
“…Reciprocally, magnetic measurements appear as an adequate tool to indirectly evaluate the electronic influence of chemicals adsorbed at the surface of NPs (which can be of interest to monitor catalytic reactions) [309].…”

“…The magnetic measurements were performed in situ using a Foner vibrating-sample magnetometer [46,47] with 20 mg catalyst loading. The magnetometer was calibrated by using 1 mg of pure metallic Fe before each experiment.…”

“…Very intriguing magnetic phenomena were found in other similar vanadate compounds [7][8][9][10][11]. It is also known from literature [12][13][14][15][16][17][18] that magnetic measurements are useful in catalytic investigations. As an example, catalytic activity of ferromagnetic or antiferromagnetic phases can change at the Curie or Neel temperatures.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
