Graphene-polypyrrole/platinum nano modified glassy carbon electrode, preparation method for same and application thereof

The invention discloses a graphene-polypyrrole/platinum nano modified glassy carbon electrode and a preparation method for the same. The preparation method particularly includes the steps of polishing a glassy carbon electrode, and preparing a grapheme modified glassy carbon electrode, a graphene-polypyrrole modified glassy carbon electrode and the graphene-polypyrrole/platinum nano modified glassy carbon electrode. The obtained graphene-polypyrrole/platinum nano modified glassy carbon electrode is used as a catalyst for methanol oxidation in a methanol fuel cell. The graphene-polypyrrole/platinum nano modified glassy carbon electrode has the advantages of high dispersion, high catalytic activity and high anti-toxicity.
