Electron beam induced transformation of MoO3 to MoO2 and a new phase MoO

The transformation of MoO3 induced by electron beam irradiation was studied by electron energy-loss spectroscopy (EELS) in combination with electron diffraction and high-resolution transmission electron microscopy (HRTEM) techniques. The routes of structure transformation were dependent on the applied electron current density. In case of low current density, MoO 2 was obtained. In case of high current density, MoO with a rock-salt structure is suggested to be the final phase. The change in oxidation states of the Mo oxides was deduced from the features in energy-loss near edge structure (ELNES) of the O K-edge. Quantitative analysis was successfully employed on Mo M3-edge and O K-edge to obtain the O/Mo ratio of the reduced phases. The mechanisms of different structure transformation behaviors were suggested in the frame of radiolysis enhanced diffusion.

Heavy water reactions with atomic transition-metal and main-group cations: Gas phase room-temperature kinetics and periodicities in reactivity

Reactions of heavy water, D2O, have been measured with 46 atomic metal cations at room temperature in a helium bath gas at 0.35 Torr using an inductively coupled plasma/selected ion flow tube tandem mass spectrometer. The atomic cations were produced at ca. 5500 K in an ICP source and were allowed to decay radiatively and thermalize by collisions with Ar and He atoms prior to reaction. Rate coefficients and product distributions are reported for the reactions of fourth-row atomic cations from K+ to Se+, of fifth-row atomic cations from Rb+ to Te+ (excluding Tc+), and of sixth-row atomic cations from Cs+ to Bi +. Primary reaction channels were observed leading to O-atom transfer, OD transfer, and D2O addition. O-Atom transfer occurs almost exclusively (≥90%) in the reactions with most early transition-metal cations (Sc+, Ti+, V+, Y+, Zr +, Nb+, Mo+, Hf+, Ta+, and W+) and to a minor extent (10%) with one main-group cation (As+). OD transfer is observed to occur only with three cations (Sr+, Ba+, and La+). Other cations, including most late transition and main-group cations, were observed to react with D 2O exclusively and slowly by D2O addition or not at all. O-Atom transfer proceeds with rate coefficients in the range of 8.1 × 10-13 (As+) to 9.5 × 10-10 (Y +) cm3 molecule-1 s-1 and with efficiencies below 0.1 and even below 0.01 for the fourth-row atomic cations V+ (0.0032) and As+ (0.0036). These low efficiencies can be understood in terms of the change in spin required to proceed from the reactant to the product potential energy surfaces. Higher order reactions are also measured. The primary products, NbO+, TaO+, MoO +, and WO+, are observed to react further with D 2O by O-atom transfer, and ZrO+ and HfO+ react further through OD group abstraction. Up to five D2O molecules were observed to add sequentially to selected M+ and MO+ as well as MO2+ cations and four to MO2D +. Equilibrium measurements for sequential D2O addition to M+ are also reported. The periodic variation in the efficiency (k/kc) of the first addition of D2O appears to be similar to the periodic variation in the standard free energy (ΔG°) of hydration.

Mass-spectrometric study of evaporation and thermodynamic properties of silica: III.1 Equilibrium reactions of molecules occurring in the gas phase over silica

The reactions of SiO, SiO2, and Si2O2 molecules occurring in the gas phase over silica at 1610-1980 K were studied by the Knudsen mass-spectrometric effusion procedure. The results were compared with published data.
