  • Method for preparing nanosponge-structured graphene dot-palladium hybrid, and nanosponge-structured graphene dot-palladium hybrid prepared thereby
    Patent number: 11955647
    Abstract: Disclosed are a method for preparing a graphene dot-palladium hybrid having a nanosponge structure that includes reducing a palladium precursor in the presence of a carbon dot and sodium bromide, and a graphene dot-palladium hybrid catalyst prepared according to the method. The nanosponge structure of the graphene dot-palladium hybrid is encapsulated by a graphene dot. The carbon dot is doped with at least one heteroatom selected from the group consisting of nitrogen, sulfur, phosphorus, and boron.
    Type: Grant
