Hydrodenitrogenation, a key step in petroleum refinement, proceeds with greater activity and large-chain selectivity on molybdenum-nitride powders than on conventional catalysts, which are alumina-supported, sulfided, Co-Mo or Ni-Mo active sites. Additional evidence suggests that δ- phase hexagonal MoN is most active, but detailed fundamental studies of phase-pure molybdenum nitrides at a scale sufficient to elucidate clear atomic and molecular level mechanistic explanations of previous materials-activity correlations have yet to be undertaken. This work includes the study of growth and characterization of hexagonal Molybdenum nitride thin films. Molybdenum nitride films were grown on Ru (0001) via ion-assisted physical vapor deposition and subsequent annealing and were characterized by X-ray photoelectron spectroscopy (XPS), low energy electron diffraction (LEED) and Scanning tunneling microscope (STM). The growth and characterization of films is also supported by Density Functional Theory calculations.
