摘要：
Adsorption kinetics and dynamics of CO2 on Ru(0001), graphene grown on Ru, and graphene oxide (GO) on Ru were studied. Graphene and GO were made in ultrahigh vacuum by benzene decomposition and subsequent atomic oxygen adsorption, respectively. The samples were characterized by AES (Auger electron spectroscopy) and XPS (X-ray photoelectron spectroscopy). As determined by TDS (thermal desorption spectroscopy), CO2 physisorbs molecularly at similar to 85 K on Ru and GO, but not on graphene. Binding energies amount to similar to 26 kJ/mol and were slightly enhanced on GO as compared with Ru. Similarly, adsorption probabilities, as determined by molecular beam scattering, are larger on GO than on Ru.
