Summary: | The present disclosure provides for a composite catalyst comprising a first catalytic material incorporated with a second catalytic material, wherein the first catalytic material comprises carbon doped with (i) nitrogen and (ii) at least one non-precious transition metal, and wherein the second catalytic material comprises a carbon-based supporting material incorporated with platinum nanoparticles. The present disclosure also provides for a method of producing the composite catalyst, wherein the method may comprise providing a mixture comprising the first catalytic material and the second catalytic material, and subjecting the mixture to a size reduction step. The first catalytic material and a method of producing the first catalytic material are disclosed herein.
La présente invention concerne un catalyseur composite comprenant un premier matériau catalytique incorporé à un second matériau catalytique, le premier matériau catalytique comprenant du carbone dopé avec (i) de l'azote et (ii) au moins avec un métal de transition non précieux, et le second matériau catalytique comprenant un matériau de support à base de carbone incorporé avec des nanoparticules de platine. La présente invention concerne également un procédé de production du catalyseur composite, le procédé pouvant comprendre la fourniture d'un mélange comprenant le premier matériau catalytique et le second matériau catalytique, et la soumission du mélange à une étape de réduction de taille. L'invention concerne également le premier matériau catalytique et un procédé de production du premier matériau catalytique. |
