The co-adsorption of benzene and Co on Co(0001)

The co-adsorption of carbon monoxide and benzene on Co(0001) has been studied using density functional calculations. We used the ordered (7 × 7) R19° surface unit cell. A comparison of the co-adsorption with CO and benzene two-dimensional networks is also given. The electronic structure reveals that...

Sumario:The co-adsorption of carbon monoxide and benzene on Co(0001) has been studied using density functional calculations. We used the ordered (7 × 7) R19° surface unit cell. A comparison of the co-adsorption with CO and benzene two-dimensional networks is also given. The electronic structure reveals that the CO orbitals interact with benzene and Co layer. Regarding the bonding, the CoCo overlap population decrease 18% after benzene adsorption and increase a little after CO adsorption with a net 14.6% decrease in the co-adsorption system. The CObenzene interaction is shown by the changes in the CO (CO) and CH (benzene) bonds.
