- - Preparation Method for Graphenedot-PtNi Hybrid with Sponge Structure and Graphenedot-PtNi Hybrid Catalyst Thereby

摘要

The present invention relates to a method for preparing a platinum-based nanocomposite having a large effective surface area, a stable and high catalytic activity, and a platinum-based catalyst prepared accordingly, in which a platinum precursor and a nickel precursor are dissolved in a carbon dot solution. The present invention relates to a method for producing a carbon dot-platinum nickel hybrid characterized by reducing and a platinum-based carbon dot-platinum nickel hybrid catalyst prepared thereby.
