  • Method of preparing catalyst containing platinum dispersed on graphene quantum dot containing carrier for direct alcohol fuel cell and catalyst obtained by this method
    Patent number: 11870081
    Abstract: The invention relates to the method of preparing catalyst based on platinum (Pt), with a low Pt content, dispersed on carrier containing graphene quantum dots (Pt/GQDs or Pt/GO-GQDs) used for fuel cell with excellent activity in the electrochemical oxidation reaction of alcohol (for example, methanol, ethanol), applied as an anode catalyst for direct alcohol fuel cell (DAFC). At the same time, the invention also refers to the catalyst obtained by this method as an anode catalyst for DAFC.
