N2 - Nitrogen was chemisorbed on an alumina (Al2O3) surface by plasma discharge of N2, and the chemical behavior of chemisorbed nitrogen was studied by temperature-programmed desorption (TPD) and infrared (IR) spectroscopy. Molecular nitrogen N2(ad) chemisorbed on an Al2O3 surface showed a high reactivity with hydrogen even at room temperature, if Pt is present on the Al2O3 surface. Hydrogenated species, NH x (ad) (x=1 or 2) and NH3(ad) were formed on the Al2O3 surface as evidenced by IR spectroscopy. It is suggested that hydrogen spill-over from the Pt surface onto the Al2O3 catalyst plays an important role in the mechanism of hydrogenation reaction.
