Adsorption and reactions of ClCH2CH2OH on clean and oxygen-precovered Cu(100): Experimental and computational studies

Article Abstract:

Temperature-programmed reaction/desorption, reflection-absorption infrared spectroscopy, and density functional theory calculations are employed to investigate the adsorption and thermal reactions of ClCH2CH2OH on clean and oxygen-precovered Cu(100) surfaces. The computational studies predict that the ClCH2CH2OH is most likely to be adsorbed at the four-fold hollow sites of Cu(100), with its C-O bond only slightly tilted away from the surface normal and with a gauche conformation with respect to the C-C bond.

Thermal decomposition and adsorption of 2-Fuoroethanol on clean and oxidized CU(100)

Article Abstract:

Temperature programmed reaction/desorption (TPR/D) and reflection-absorption infrared spectroscopy (RAIRS) are used to investigate the adsorption orientation and thermal reactions of 2-fluoroethanol on clean and oxidized Cu(100). Results show that the molecular desorption predominates in heating 2-fluoroethanol adsorbed on clean and oxidized Cu(100).

Isolation and thermal reactions of the intermediates from BrCH2CH2OH decomposition on Cu(100) and oxygen-protected Cu(100)

Article Abstract:

An investigation was conducted on the reactions of BrCH2CH2OH on clean and oxygen-precovered Cu(100) surfaces under ultrahigh vacuum conditions. A study was performed on the reflection-absorption infrared spectroscopy (RAIRS) to examine the surface intermediates that were generated from BrCH2CH2OH decomposition.
