An Infrared Spectroscopic and Temperature-Programmed Desorption Study of 1,1-Difluoroethylene on Clean and Hydrogen-Covered Pd(111)
The surface chemistry of 1,1-difluoroethylene was studied on clean and hydrogen-covered Pd(111) using a combination of temperature-programmed desorption and reflection absorption infrared spectroscopy (RAIRS) to explore whether the larger infrared absorbance of 1,1-difluoroethylene than ethylene may...

| description | The surface chemistry of 1,1-difluoroethylene was studied on clean and hydrogen-covered Pd(111) using a combination of temperature-programmed desorption and reflection absorption infrared spectroscopy (RAIRS) to explore whether the larger infrared absorbance of 1,1-difluoroethylene than ethylene may be used to examine reactions under realistic catalytic conditions using RAIRS. It was found that the chemistry of 1,1-difluoroethylene on Pd(111) surfaces is similar to that of ethylene with bonding occurring in both the π- and di-σ-forms. However, due to the presence of C–F bonds in the molecule, the infrared absorbances for 1,1-difluoroethylene were much larger than those for ethylene. This provides the potential for using RAIRS for in situ studies of catalytic reactions that involve alkenes. |
