Book Description
Mossbauer spectroscopic studies have provided a reasonably consistent picture of the structure and chemistry of iron exchanged Y zeolite. It has been demonstrated that the oxidation-reduction behavior of ferric and ferrous exchanged Y Zeolite is related and that the same chemical states of iron are formed in both materials. The reversible oxidation of the zeolite iron ions by oxygen adsorption may have important implications for catalytic oxidation. The exchange of iron ions into zeolites with different structures and silicon to aluminum ratios and the observations of reversible oxidation may allow the preparation of oxidation catalysts with unique properties and selectivity.

Porous Materials in Environmentally Friendly Processes

Porous Materials in Environmentally Friendly Processes PDF Author: I. Kiricsi
Publisher: Elsevier
ISBN: 0080539289
Category : Science
Languages : en
Pages : 841

Book Description
To leave our planet liveable in the next millennium mankind is forced to find environmentally friendly ways in solving the problems of everyday life. Among others, technologies of producing chemicals, absolutely necessary for maintaining a comfortable life, have to be modified, in some instances fundamentally changed now, or in the very near future. Developing new technologies requires strong and innovative fundamental research. In order to provide opportunity for crossfertilization the Federation of European Zeolite Associations (FEZA) decided to organise a conference, where researchers from academia as well as industry can meet, exchange ideas, show and discuss research efforts and results concerning the development of environmentally friendly processes and technologies. The conference, and thus the proceedings are divided into two main parts. The first part contains works concerning the synthesis, modification and characterisation of zeolitic materials as catalyst candidates in environmentally friendly technologies. Works in the second part describe various applications starting from developing highly selective reactions for the fine chemical industry, through waste-water treatment to applying zeolite for formulating bacteria for pest control.

Heterogeneous Catalysts

Heterogeneous Catalysts PDF Author: Wey Yang Teoh
Publisher: John Wiley & Sons
ISBN: 352781356X
Category : Technology & Engineering
Languages : en
Pages : 768

Book Description
Presents state-of-the-art knowledge of heterogeneous catalysts including new applications in energy and environmental fields This book focuses on emerging techniques in heterogeneous catalysis, from new methodology for catalysts design and synthesis, surface studies and operando spectroscopies, ab initio techniques, to critical catalytic systems as relevant to energy and the environment. It provides the vision of addressing the foreseeable knowledge gap unfilled by classical knowledge in the field. Heterogeneous Catalysts: Advanced Design, Characterization and Applications begins with an overview on the evolution in catalysts synthesis and introduces readers to facets engineering on catalysts; electrochemical synthesis of nanostructured catalytic thin films; and bandgap engineering of semiconductor photocatalysts. Next, it examines how we are gaining a more precise understanding of catalytic events and materials under working conditions. It covers bridging pressure gap in surface catalytic studies; tomography in catalysts design; and resolving catalyst performance at nanoscale via fluorescence microscopy. Quantum approaches to predicting molecular reactions on catalytic surfaces follows that, along with chapters on Density Functional Theory in heterogeneous catalysis; first principles simulation of electrified interfaces in electrochemistry; and high-throughput computational design of novel catalytic materials. The book also discusses embracing the energy and environmental challenges of the 21st century through heterogeneous catalysis and much more. Presents recent developments in heterogeneous catalysis with emphasis on new fundamentals and emerging techniques Offers a comprehensive look at the important aspects of heterogeneous catalysis Provides an applications-oriented, bottoms-up approach to a high-interest subject that plays a vital role in industry and is widely applied in areas related to energy and environment Heterogeneous Catalysts: Advanced Design, Characterization and Applications is an important book for catalytic chemists, materials scientists, surface chemists, physical chemists, inorganic chemists, chemical engineers, and other professionals working in the chemical industry.

Plasma Catalysis

Plasma Catalysis PDF Author: Annemie Bogaerts
Publisher: MDPI
ISBN: 3038977500
Category : Technology & Engineering
Languages : en
Pages : 248

Book Description
Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.
