Metal—oxygen bond strength

Tethwisch, D.G. and Dumesic, J.A. (1986) Effect of metal-oxygen bond strength on properties of oxides. 1. Infrared spectroscopy of adsorbed carbon monoxide and carbon dioxide, Langmuir, 2, 73. [Pg.137]

The application of 170 NMR spectroscopy to obtain structural information about polyoxoanions, mainly in nonaqueous solution, had been examined and discussed in detail (99). A very useful finding was that chemical shifts are determined largely by metal-oxygen bond strengths. An inverse correlation exists between the 170 shift and the shortest bond length to a given metal. In aqueous solution the existence of [Mo7024]6 could be confirmed by the use of 170 and "Mo NMR spectroscopy (100-104). Evidence for the existence of the three... [Pg.151]

Selectivity and Metal-Oxygen Bond Strength. The metal-oxygen bond strength could be measured as the differential heats of reoxidation of the reduced... [Pg.396]

If these data are accepted as relevant, at least for the reduction process one of Sachtler and de Boer s conclusions (i.e., that activity should decrease with increasing metal oxygen bond strength) appears confirmed. [Pg.265]

The crystal face dependence and the activity of the various group 8-10 metals can be understood in terms of the metal-oxygen bond strength. On an active metal both O2 and H2 are dissociatively adsorbed, oxides are not formed under reaction conditions, and the heat of adsorption for Oacisis relatively low. [Pg.135]

Zhang electronegativity, and metal-oxygen bond strengths for the cations included in this study. [Pg.117]

Procedure (B) was performed based on 5 different redox metal oxides which had proven to be catalytically active towards propene formation as a result of procedure A and 3 additional metal oxides of strong metal oxygen bond strength i. e., MgO of basic nature, B2O3 of acidic nature and LajOs on which dissociative oxygen adsorption takes place. [Pg.57]
