Structure-Activity and Selectivity Relationships in Heterogeneous Catalysis
Author: R.K. GrasselliPublisher: Elsevier
ISBN: 0080887198
Category : Science
Languages : en
Pages : 375
Book Description
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.

Languages : en
Pages : 554
Book Description
Heterogeneous Catalysis: Materials and Applications focuses on heterogeneous catalysis applied to the elimination of atmospheric pollutants as an alternative solution for producing clean energy and the valorization of chemical products. The book helps users understand the properties of catalytic materials and catalysis phenomena governing electrocatalytic/catalytic reactions, and – more specifically – the study of surface and interface chemistry. By clustering knowledge in these fields, the book makes information available to both the academic and industrial communities. Further, it shows how heterogeneous catalysis applications can be used to solve environmental problems and convert energy through electrocatalytic reactions and chemical valorization. Sections cover nanomaterials for heterogeneous catalysis, heterogeneous catalysis mechanisms, SOX adsorption, greenhouse gases conversion, reforming reactions for hydrogen production, valorization of hydrogen energy, energy conversion and biomass valorization. - Addresses topics of increasing interest to society such as the valorization of biomass, the use of polluting gases to produce value-added products, and the optimization of catalytic materials for water splitting, fuel cells, and other devices - Discusses pollutant adsorption by industrial fume desulphurization processes - Helps improve processes for obtaining chemicals using nonconventional technologies
Construction and Reactivity of Pt-Based Bi-component Catalytic Systems
Author: Rentao MuPublisher: Springer
ISBN: 3662552442
Category : Science
Languages : en
Pages : 99
Book Description
In this thesis, the author outlines the construction of active structure and modulation of catalytic reactivity of Pt-based bi-component catalysts, from the model systems to real supported catalysts. The thesis investigates the promotion effect of the second components on catalytic performance of Pt catalysts, and presents the reversible generation of the “sandwich-like” structure of Pt-Ni catalysts, containing both surface NiO1-X and subsurface Ni by alternating redox treatments at medium temperature. With the aid of single layer graphene, the dynamic process of chemical reactions occurring on the Pt(111) surface can be visualized using in-situ LEEM and DUV-PEEM techniques, the results of which are included here. The author reveals that the graphene layer exhibits a strong confinement effect on the chemistry of molecules underneath and the intercalated CO can desorb from the Pt surface around room temperature and in UHV, which may promote the CO oxidation confined under graphene.
