Abstract
(EN)
Embodiments of the present invention provide a C2N graphene-precious metal composite nanometer catalyst, comprising a C2N graphene carrier and catalytically active precious metal nanoparticles attached to a surface of the C2N graphene carrier. The precious metal nanoparticles are uniformly distributed on the surface of the C2N graphene carrier by coordinating with nitrogen atoms in the C2N graphene carrier. The C2N graphene is used as a carrier in the catalyst, and therefore, the precious metal nanoparticles can be uniformly dispersed on the surface of the graphene by a high-loading amount, so that the catalyst has excellent performances such as high activity, high thermal stability, and high mechanical strength, thereby finally improving power performances and prolonging service lives of fuel battery and metal air battery. The embodiments of the present invention further provide a preparation method for the C2N graphene-precious metal composite nanometer catalyst.

Des modes de réalisation de la présente invention concernent un catalyseur nanométrique composite graphène C2N/métal précieux comprenant un support de graphène C2N et des nanoparticules de métal précieux catalytiquement actives fixées à une surface du support de graphène C2N. Les nanoparticules de métal précieux sont uniformément réparties sur la surface du support de graphène C2N par coordination avec des atomes d'azote dans le support de graphène C2N. Le graphène C2N est utilisé comme support dans le catalyseur, et par conséquent les nanoparticules de métal précieux peuvent être uniformément dispersées sur la surface du graphène par une quantité de charge élevée, de sorte que le catalyseur présente d'excellentes performances telles qu'une activité élevée, une stabilité thermique élevée et une résistance mécanique élevée, ce qui permet finalement d'améliorer les performances de puissance et de prolonger la durée de vie de batteries de piles à combustible et d'accumulateurs métal-air. Les modes de réalisation de la présente invention concernent en outre un procédé de préparation pour le catalyseur nanométrique composite graphène C2N/métal précieux.
