Book excerpt: We have performed a resonant photoemission study on both stoichiometric and defect TiO2 (110) surfaces using synchrotron radiation. A resonant enhancement of the O(2p) valence band photoemission intensity is observed for both nearly Perfect and reduced TiO2 surfaces as the photon energy is swept through the Ti 3p ≥ 3d optical transition energy, which indicates a strong hybridization between the O and Ti ions. Changes in the shape of the O(2p) band are also observed. As compared to the nearly perfect surface, the reduced surface has higher emission intensity from the bonding orbitals relative to the nonbonding orbitals. In addition, the intensity of emission from the O(2p) bonding orbitals resonates more than that from the O(2p) nonbonding orbitals for both nearly perfect and reduced surfaces. The resonant enhancement for the O(2p) bonding orbitals is consistent with theoretical calculations, which predict that the O(2p)-Ti(3d) hybridization involves primarily those O(2p) orbitals; the origin and energy dependence of the resonant enhancement for the O(2p) nonbonding orbitals are not understood. The spectra for the defect surface exhibit a resonant change in the intensity of the Ti(3d) emission as well, which is similar to those reported for Ti2O3, SrTiO{sub 3-x} and Ti metal.

Download or read book Structure Activity and Selectivity Relationships in Heterogeneous Catalysis written by R.K. Grasselli and published by Elsevier. This book was released on 1991-07-09 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structure plays an important role in heterogeneous catalysis. It provides a framework for the arrangement and stragetic placement of key catalytic elements, hosting them in a prescribed manner so that their respective electronic properties can exhibit their desired catalytic functions and mutual interactions. Under reaction conditions these framework structures and their catalytic guests undergo dynamic processes becoming active participants of the overall catalytic process. They are not mere static geometric forms. The dynamics of catalytic structures are particularly vivid in selective oxidation catalysis where the lattice of a given catalytic solid partakes as a whole, not only its surface, in the redox processes of the reaction. The catalyst becomes actually a participating reagent. By proper choice of key catalytic elements and their host structures, preferred catalytic pathways can be selected over less desired ones. However, not only in selective redox catalysis does structure play an important role, its importance is also well documented, among others, in shape selective zeolite catalysis, enantioselective hydrogenation and hydrodesulfurization. The contributions presented in this book address the dynamic character of the solid state under catalytic reaction conditions. By relating structure to activity and selectivity in heterogeneous catalysis our understanding of such correlations has been significantly enhanced through the use of sophisticated spectroscopic means, surface science and modeling.

This book was released on 2017-10-23 with total page 3912 pages. Available in PDF, EPUB and Kindle. Book excerpt: This most comprehensive and unrivaled compendium in the field provides an up-to-date account of the chemistry of solids, nanoparticles and hybrid materials. Following a valuable introductory chapter reviewing important synthesis techniques, the handbook presents a series of contributions by about 150 international leading experts -- the "Who's Who" of solid state science. Clearly structured, in six volumes it collates the knowledge available on solid state chemistry, starting from the synthesis, and modern methods of structure determination. Understanding and measuring the physical properties of bulk solids and the theoretical basis of modern computational treatments of solids are given ample space, as are such modern trends as nanoparticles, surface properties and heterogeneous catalysis. Emphasis is placed throughout not only on the design and structure of solids but also on practical applications of these novel materials in real chemical situations.

This book was released on 2012-12-06 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprises the proceedings of a NATO sponsored Advanced Research Workshop held from 1st November to 6th November 1992 in the delightful Chateau de Florans, Bedoin, Vaucluse, France and entitled 'Elementary Reaction Steps in Heterogeneous Catalysis. ' The organisers are grateful to the Science Committee of NATO for their support of this meeting. This is believed to be the first wide ranging NATO ARW in the field of heterogeneous catalysis for 20 years, following a previous venture organised in Sardinia by Basolo and Burwell, of Northwestern University, Illinois, USA [1]. This volume collects the lecture presentations and reports on the lively Panel discussions. The idea for the meeting evolved from a series of International Symposia on Quantum Chemistry and Mechanism in Heterogeneous Catalysis. The first of these was held in Lyon, France in 1986, the second in Krakow, Poland in 1988 and the third in Berkeley, California in 1990. The organising committee of the present meeting was Bernard Bigot, France, Tony Farragher, Netherlands, Richard Joyner, UK, Mme. Danielle Olivier, France, and Rutger van Santen, Netherlands, (Chairman). We wish to thank all members of the committee but in particular Bernard Bigot, who undertook the very extensive work involved in the local organisation with consummate skill and made our stay in Provence a great pleasure. Bernard Bigot's secretary, Mme. Marie-Noelle Coscat and Richard Joyner's secretary, Mrs. Pat Gibbs, also deserve our considerable thanks. There were fifty-four participants from eleven countries.

Download or read book Molecular Heterogeneous Catalysis written by Rutger A. van Santen and published by John Wiley & Sons. This book was released on 2009-06-10 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrated approach to the molecular theory of reaction mechanism in heterogeneous catalysis, largely based on the knowledge among the growing theoretical catalysis community over the past half century, and covering all major catalytic systems. The authors develop a general conceptual framework, including in-depth comparisons with enzyme catalysis, biomineralisation, organometallic and coordination chemistry. A chapter dedicated to molecular electrocatalysis addresses the molecular description of reactions at the liquid-solid interphase, while studies range from a quantum-chemical treatment of individual molecular states to dynamic Monte-Carlo simulations, including the full flexibility of the many-particle systems. Complexity in catalysis is explained in chapters on self-organization and self-assembly of catalysts, and other sections are devoted to evolutionary, combinatorial techniques as well as artificial chemistry.
