Özet
Adsorption studies of hydrogen and deuterium on the clean (100) surface of aluminum are reported. The probability for H 2 (D 2) dissociation and subsequent metal-hydrogen bond formation is less than 1: 10 4. This prompted the use of a beam of atomic hydrogen (deuterium). We have adsorbed between 0.01 and 1.0 monolayer and studied annealing sequences between 80 and 750 K with electron-energy-loss spectroscopy (EELS) and thermal-desorption spectroscopy (TDS). At< 90 K we observe surface hydrogen coordinated in bridge positions, characterized by an Al-H (-D) vibrational band at 1125 (800) cm− 1. Annealing to 150 K causes dominant features to appear at 1750 (1250) and 750 (550) cm− 1. These losses are interpreted as the stretching and bending and/or scissoring modes of a terminally coordinated species. Further annealing to 280 K sees the growth of an intense band at 1825 (1325) cm− 1 …
