Abstract

A uniform and thin layer of polyaniline (PANI) was fabricated through an in situ introduction of aniline during a microwave process combined with polymerization. Coating a Pt catalyst with PANI improved the electronic structure and protected the Pt, enhancing the activity and stability of the catalyst.
