Abstract:
A multi-potential step method is proposed for constructing flexible PPy/Rh film electrodes. The obtained PPy/Rh films exhibit excellent hydrogen evolution reaction (HER) catalytic performance and can be used as flexible electrodes that maintain their initial catalytic performance after bending. Characterization shows that the active sites of the catalyst are due to electron transfer between Rh and PPy.
