The structures and reactions of linear and cyclic C6 hydrocarbons adsorbed on the Pt(111) crystal surface studied by sum frequency generation vibrational spectroscopy: Pressure, temperature, and H2 coadsorption effects
Article Abstract:
A study on the adsorption structures and reactions of C6 hydrocarbons molecules on Pt(111) using sum frequency generation (SFG) vibrational spectroscopy is presented. The SFG results showed that in the absence of excess hydrogen, the cyclohexene reaction on Pt(111) is dictated by bimolecular reactions between surface species and cyclohexene reactant.

High-coverage structures of carbon monoxide adsorbed on Pt(111) studied by high-pressure scanning tunneling microscopy
Article Abstract:
The room-temperature adsorption of CO on a Pt(111) single-crystal surface in equilibrium with the gas phase is studied using high-pressure scanning tunneling microscopy. The CO adsorbate layer is continuously compressed with increasing pressure, resulting in a continuous coverage variation form 0.5 to 0.7.

UV-induced desorption-retrapping cycle of electrochemically adsorbed CO on Pt(111) surface
Article Abstract:
CO adsorbed layer of Pt(111) electrode undergoes reconstruction when exposed to UV-irradiation (266 nm) from a nanosecond or femtosecond laser. UV induce CO desorption and retrapping cycles, which passed through electronic excited states at the surface were sustained on the electrode surface.
