The thermal decomposition of methanol and methanethiol on the clean and modified Fe(110) surface
- Harvard Univ., Cambridge, MA (United States)
The thermal decomposition of methanol and methanethiol on the clean and modified Fe(110) surface has been examined using X-ray photoelectron spectroscopy, low-energy electron diffraction and temperature programmed reaction spectroscopy. Both methanethiol and methanol adsorb on the Fe(110) surface at 100 K with immediate cleavage of the terminal hydrogen to produce methylthiolate (CH{sub 3}S) and methoxy (CH{sub 3}O) coadsorbed with atomic hydrogen on the Fe surface. Heating the sample to 800 K produces gas phase methane and hydrogen, leaving a chemisorbed S overlayer in the case of methylthiolate, while methoxy decomposes via desorbing hydrogen and CO to leave a clean Fe surface. The influence of oxygen and sulfur pre-adsorption on the thermal decomposition of these species will also be described.
