Graphene-poly(5-aminoindole) composite film as Pt catalyst support for methanol electrooxidation in alkaline medium

- Electropolymerization of 5-aminoindole (AIn) in the presence of graphene (GE).
- Significant catalytic effect of GE on the polymerization of AIn.
- PAIn/GE/GC used as Pt catalyst support.
- The enhanced catalytic activity of Pt/PAIn/GE/GC for methanol electrooxidation.
