Titelbeschreibung

Reactive, but not a reactant. Heterogeneous catalysts play an unseen role in many of today's processes and products. With the increasing emphasis on sustainability in both products and processes, this handbook is the first to combine the hot topics of heterogeneous catalysis and clean technology. It focuses on the development of heterogeneous catalysts for use in clean chemical synthesis, dealing with how modern spectroscopic techniques can aid the design of catalysts for use in liquid phase reactions, their application in industrially important chemistries - including selective oxidation, hydrogenation, solid acid- and base-catalyzed processes - as well as the role of process intensification and use of renewable resources in improving the sustainability of chemical processes. With its emphasis on applications, this book is of high interest to those working in the industry.

Autorenportrait

Dr Wilson was educated at the Universities of Cambridge (PhD supervisor: Prof. Richard Lambert) and Liverpool. She moved to York in 1998, undertaking post-doctoral research on new mesoporous solid acids with Prof. James Clark, and was subsequently appointed to a lectureship at York in 1999. Karen was promoted to Senior Lecturer in 2007, prior to her appointment as Reader in Physical Chemistry at Cardiff University. Her research interests lie in the design of hierarchical porous solid catalysts for clean chemical synthesis, particularly the development of tuneable solid acids and bases for sustainable bio-diesel synthesis. She has recently been awarded a Royal Society Industry fellowship to work on new catalysts for biofuel production. Prof Lee carried out undergraduate and postgraduate studies at the University of Cambridge (PhD supervisor: Prof. Richard Lambert). He was appointed to a lectureship at the University of Hull in 1996, before moving to the University of York where he was promoted to Senior Lecturer (2006). In 2009, Adam was awarded an EPSRC Leadership Fellowship and appointed Professor of Physical Chemistry at Cardiff University. His research interests lie in the design of tailored nanocatalysts for green chemistry, and the development of in situ methodologies to provide mechanistic insight into surface processes.
