Chemistry of cyclopropane on Pt(111): thermal, electron, and photon activation
Article Abstract:
Temperature-programmed desorption, X-ray photoelectron spectroscopy and high-resolution electron energy loss spectroscopy were used to investigate the thermal, electron and photon-induced chemistry of c-C3H6 adsorbed on Pt(111) at 100 K. Monolayer c-C3H6 was found to adsorb without dissociation on Pt(111) at 100 K and desorb molecularly at 144 K. Results also showed that the nonthermal chemistry is activated by either 50 eV of 6.4 eV photon irradiation.

Photochemistry of iodobenzene adsorbed on sapphire (0001)
Article Abstract:
A study was conducted to characterize the thermal chemistry and x-ray and 193 nm photochemistry of C6H4I on Al2O3(0001). The study was carried out in a UHV system supporting a base pressure of 2x10(super -10) Torr. Low-energy excimer laser pulses were incident through a LiF for photolysis. Results indicated that photon irradiation supported dissociation. In addition, the amount of benzene formed increased monotonically with 193 nm irradiation.

Stepwise dissociation of thermally activated phenol on Pt(111)
Article Abstract:
Phenol surface chemistry is interesting because when its reactions are catalyzed by metals, there can be a number of different initial bond-breaking processes. Using various deuterium-labeled forms, the thermal reaction chemistry is studied of phenol on Pt(111) with temperature-programmed desorption (TPD), high-resolution electron energy loss spectroscopy (HRELLS) and X-ray photoelectron spectroscopy (XPS).
