  Electric field is an effective route to tune the performance of catalysts.Here,we have probed the change of CO/O2 adsorption,the reaction mechanism of CO oxidation on Mn-doped graphene as a result of the externally applied electric field and provided a theoretical understanding of the rule by density functional theory(DFT)calculation.
