▎ 摘　　要

Adsorptions of CO on pristine, Fe-, Ru-, Os-, Co-, Rh-, Ir-, Ni-, Pd-, and Pt-doped graphene were investigated, using density functional theory calculation at B3LYP/LanL2DZ theoretical level. This work revealed that the transition metal doped graphenes were more highly sensitive to CO adsorption than that of pristine graphene. The Os- and Fe-doped graphenes displayed the strongest interaction with C and O atoms of CO molecule, respectively. (c) 2014 Elsevier Ltd. All rights reserved.
