Abstract
L'invention concerne des catalyseurs et leurs procédés de production, ces catalyseurs pouvant être utilisés dans des électrodes pour des capteurs électrochimiques de gaz, pour des piles à combustible et dans des réactions de déshydrogénation d'hydrocarbures. Le procédé de production de catalyseur de l'invention consiste à ajouter une suspension aqueuse de nanodiamant, ayant une superficie spécifique de 200 à 600 m2/g et une teneur en nanodiamant de 20 à 85 % en masse par rapport à un métal pur, à la solution aqueuse de complexes de métaux du groupe platine et du formiate de lithium, et d'effectuer une synthèse à une température comprise entre 20 et 40 °C à un pH de 7 et à une concentration acide/sel dans la solution comprise entre 10-3 et 5⋅10-3 mole/litre. Les catalyseurs présentent une haute sélectivité lorsqu'ils sont utilisés dans des électrodes de test des capteurs électrochimiques de gaz, tel que le CO, et un haut rendement dans les processus de déshydrogénation d'hydrocarbures.
