Ceria-based oxides have gained a major position in the list of non-innocent supports, active co-catalysts and advanced materials, mainly for environmental applications and for energy conversion systems. The new century has confirmed the unique and irreplaceable role of ceria and ceria–zirconia in advanced car converters for exhaust gas pollution control. Parallel to this worldwide application, these materials have a bright future in many new sectors, including as catalysts in hydrogen production and purification and in fuel cells (either as electrolytes or catalytic materials) and even as photocatalysts. Consistently, the course will cover the fundamentals of cerium dioxide exposing students to relevant topics in chemistry, materials science, catalysis and chemical engineering. The final aim is of highlighting cutting-edge research priorities and discussing the state of the art developments in this field. Contents will be divided in two main sections: 1. Fundamental aspects of ceria based materials; 2. Catalytic applications of ceria based materials. Lecture topics will cover: - Structural aspects - Preparation - Characterization - Theory / Modelling / simulation - Redox-Oxygen storage properties - Core-shell systems - Biocatalysis - Applications (Solid Oxides Fuel Cells, Oxygen Membranes, Combustion Catalysis, Water Gas Shift Reaction…..). The school will draw on the knowledge and expertise of a group of internationally renowned scientists currently working at the leading edge of chemistry and catalysis by cerium dioxide based materials. These courses are designed for MSc-students, PhD-students, Post-Doctorate and young researchers. However, attendance will benefit all those interested in the key research and development issues facing ceria based materials science and technology: young professionals working at the forefront of catalysis or entering in the field, experienced researchers wishing to review the technology addressed and expand their knowledge on application of ceria in catalysis. The workshop is also aimed at science and engineering faculty whose expertise lie in other fields and are looking to enter the field of ceria-based catalysts.
