In this communication, we propose physical mechanism of plasmon‐exciton codriven surface catalytic reaction, based on the electrochemical graphene mediated surface‐enhanced Raman scattering spectroscopy. It is found that with the help of graphene, the Fermi Level of the graphene‐roughened Ag electrode hybrid system can be significantly increased, which can efficiently promote the efficiency of surface catalytic reaction compared with that driven by roughened Ag electrode alone.
