Abstract
The adsorption and reactions of HOCH2CH2NH 2 on oxygen-precovered Cu(100) were investigated under ultrahigh vacuum conditions. Reflection-absorption infrared spectroscopy (RAIRS) studies were performed to monitor and identify the surface intermediates from HOCH 2CH2NH2 decomposition, with the assistance of density functional theory (DFT) calculations. -OCH2CH2NH- was generated from scission of both the O-H and N-H bonds of HOCH 2CH2NH2 and decomposed to form surface -OCH2CH2N- and to evolve CH2O and HCN observed with temperature-programmed reaction/desorption (TPR/D). The -OCH 2CH2N- species further decomposed to generate H 2, HCN, and N2, together with surface carbon. The bonding structures of the two surface intermediates, -OCH2CH2NH- and -OCH2CH2N-, were also investigated by DFT calculations.
