Claim 19:
20. The catalyst of claim 13, wherein step 2, to obtain the catalyst based on Pt dispersed on the carrier containing a mixture of graphene oxide and graphene quantum dots, it is possible to conduct the reaction under the effect of microwaves by adding ethylene glycol 99.5% to the GO-GQDs mixture obtained in step 1 a.2, with the volume ratio of ethylene glycol solution to the volume of the mixture containing GO-GQDs ranging from about 2:1 to 7:1, conduct transducer ultrasound reaction, for about 1 minute to 12 minutes, obtaining EG-GO-GQDs mixture; then, add H2PtCl6 0.01 M solution to the EG-GO-GQDs mixture, with a volume ratio of H2PtCl6 0.01 M solution compared to the volume of the GO-GQDs mixture ranging from about 1:5 to 1:97 and transfer the mixture to a microwave reactor, heating the mixture to about 200° C. for 20 to 30 minutes; keep thermally stable from 10 to 60 minutes, cool down the mixture to room temperature; centrifuging to obtain a solid product, then wash several times with demineralized water and dry in a vacuum, obtaining a catalyst based on Pt dispersed on carrier containing a mixture of graphene oxide and graphene quantum dots in the form of solid used as anode catalyst for DAFC.
