Abstract

AbstractMechanism of reduction of MoO3 in hydrogen was studied by photoelectron spectroscopy. Four different doublets corresponding to Mo/3d/ electrons were observed depending on the degree of reduction. Binding energy EB in Mo+6 was found to be 231.5 and 234.7 eV. On reduction isolated Mo+4 ions are at first formed with EB = 230.1 and 233.2 eV. Then clusters of edge‐sharing octahedra on shear planes are formed in which pairing of Mo+4 ions occurs due to metal‐metal bonding with Mo/3d/ EB amounting to 228.2 and 231.4 eV. UPS spectra show that the Mo+4 ions constitute two types of donor levels in the forbidden energy gap. In very advanced stage of reduction metallic molybdenum appears at the surface with EB = 226.8 and 230.0 eV.
