Abstract:
Nitrogen was chemisorbed on an alumina ( Al 2 O 3 ) surface by plasma discharge of N 2 , and the chemical behavior of chemisorbed nitrogen was studied by temperature-programmed desorption (TPD) and infrared (IR) spectroscopy. Molecular nitrogen N 2 (ad) chemisorbed on an Al 2 O 3 surface showed a high reactivity with hydrogen even at room temperature, if Pt is present on the Al 2 O 3 surface. Hydrogenated species, NH x (ad) ( x =1 or 2) and NH 3 (ad), were formed on the Al 2 O 3 surface, as evidenced by IR spectroscopy. It is suggested that hydrogen spill-over from the Pt surface onto the Al 2 O 3 catalyst plays an important role in the mechanism of hydrogenation reaction.
