Abstract

Nitrogen was chemisorbed on a Pt/Al₂O₃ catalyst by a plasma discharge of N₂, and the chemical reactivity of the chemisorbed nitrogen with hydrogen was studied by temperature-programmed desorption (TPD) and infrared (IR) spectroscopy. The adsorbed nitrogen was desorbed at around 200°C by TPD, and a part of the adsorbed species was reacted with hydrogen to form NH₃. IR spectroscopy showed an absorption band at 2260 cm⁻¹, which was assigned to N-N streching of molecular N₂(a) chemisorbed mainly on the Al₂O₃ support. It was suggested that the N₂(a) reacted with the spiltover hydrogen from Pt surface even at room temperature.
