Concepts in Catalysis by Transition Metal Oxides,molecule, influencing its reactivity along different reaction pathways and determining thus the selectivity. Geometry of catalyst surface and its composition, differing from that of the bulk, are important factors in determining the structure of the complex. Dispersion of the active phase strongly i

Bulk and Surface Structures of Non-Metals,on, phase equilibria and the structures of stoichiometric compounds are discussed with emphasis placed upon the determination of the crystal structure types likely to form in any particular system. The second section deals with doping and gives an overall review of non-stoichiometric phases, and the

Physical Methods for the Characterization of Non-Metal Catalysts,rt. They are classified as a function of the nature and energy of the incident and/or the emitted beam. Their main properties and limitations are considered and compared. The usefulness of several physical techniques for better characterizing a catalyst is particularly emphasized. Some examples are

UV-Visible Diffuse Reflectance Spectroscopy Applied to Bulk and Surface Properties of Oxides and Reelka-Munk equation is derived and the experimental technique required for diffuse reflectance work is discussed. Application to non-metallic solids is illustrated first with reference to spectra arising from . transitions and then with regard to charge-transfer spectra. Particular attention is given

Selective Oxidation and Ammoxidation Catalysis: History of Catalyst Design,f the total volume of the top twenty organic chemicals produced. These processes may be classified as allylic, aromatic, and paraffinic oxidation, and epoxidation. The major allylic oxidation process is the ammoxidation of propylene, which accounts for all of the over eight billion pounds of acrylon

Selective Oxidation and Ammoxidation Catalysis: Mechanism and Commercial Practice,rmation of a radical-like Mo-complexed π-allylic intermediate .rate-determining H- abstraction by Bi-O. Subsequent O-insertion by the Mo=O moiety of a dioxo species forms a σ-O allyl complex, the acrolein precursor,. In ammoxidation analogous π-and σ-allyl species lead to acrylonitrile after activat
