An IR study on selective hydrogenation of 1,3-butadiene on transition metal nitrides: 1,3-butadiene and 1-butene adsorption on Mo2N/gama-Al2O3 catalyst
Article Abstract:
The surface species derived from the adsorption of 1,3-butadiene and 1-butene on Mo2N/gama-Al2O3 catalyst are characterized by in situ FT-IR spectroscopy with an attempt to get insight into the selective hydrogenation of 1,3-butadiene on transition metal nitride catalysts. The high selectivity of 1,3-butadiene hydrogenation to 1-butene is mainly because of the competitive adsorption of the surface species; namely, the pi (sub d) -adsorbed butadiene strongly prevents 1-butene from its adsorption and further hydrogenation.

In situ FT-IR spectroscopic studies of CO adsorption of fresh Mo2C/AI2O3 catalyst
Article Abstract:
The surface nature of fresh Mo2C/AI2O3 and reduced passivated Mo2C/AI2O3 are studied by using in situ IR spectroscopy using CO as the probe molecule. Adsorbed CO on the reduced passivated Mo2C/AI2O3 catalyst gives a main band at 2180 cm-1, which can be assigned to linearly adsorbed CO on Mo4+ sites and the results show that the surface of reduced passivated sample is dominated by molybdenum oxycarbide.

Low-temperature isomerization of 1-butene on Mo2N/gamma-Al2O3 catalyst studied by in situ FT-IR spectroscopy
Article Abstract:
The adsorption and reaction of 1-butene on Mo2N/gamma-Al2O3 catalyst are studied by in situ FT-IR spectroscopy at low temperatures. The result of coadsorption of 1-butene with CO indicates that 1-butene is mainly adsorbed on the surface Mo sites of the nitrided catalyst.
