Abstract
The adsorption and thermal decomposition of N-methylaniline (NMA) on the Pt(1Â 1Â 1) surface has been studied with reflection absorption infrared spectroscopy (RAIRS), temperature programmed desorption (TPD), and X-ray photoelectron spectroscopy (XPS). NMA adsorbs molecularly at 85Â K through the nitrogen lone pair and is stable up to 300Â K. At temperatures of 300-350Â K it converts to two or more surface intermediates including the N-methyleneaniline (NMEA) species. This NMEA intermediate dissociates upon annealing to 450Â K, and further annealing leads to the desorption of HCN and H2, leaving only C on the surface at 800Â K.
