Facile fabrication of PtCuAu nanoparticles modified reduced graphene oxide with high electrocatalytic activity toward formic acid oxidation

- The PtCuAu/RGO was fabricated by electrochemical method.
- PtCuAu nanoparticles were uniformly electrodeposited on the RGO surface.
- The PtCuAu/RGO showed high catalytic activity for formic acid electrooxidation.
