Abstract :

Ceria has been the subject of thorough investigations, mainly because of its use as an active component of catalytic converters for the treatment of exhaust gases. However, ceria-based catalysts have also been developed for different applications in organic chemistry. The redox and acid–base properties of ceria, either alone or in the presence of transition metals, are important parameters that allow to activate complex organic molecules and to selectively orient their transformation. Pure ceria is used in several organic reactions, such as the dehydration of alcohols, the alkylation of aromatic compounds, ketone formation, and aldolization, and in redox reactions. Ceria-supported metal catalysts allow the hydrogenation of many unsaturated compounds. They can also be used for coupling or ring-opening reactions. Cerium atoms can be added as dopants to catalytic system or impregnated onto zeolites and mesoporous catalyst materials to improve their performances. This Review demonstrates that the exceptional surface (and sometimes bulk) properties of ceria make cerium-based catalysts very effective for a broad range of organic reactions.

Biographical Information

Laurence Vivier obtained her Ph.D. in chemistry from the University of Poitiers (France) in 1991. Following a post-doctoral stay at the University of Swansea (UK), she returned to Poitiers at the Laboratoire de Catalyse en Chimie Organique as an Assistant Professor. Her research focuses on hydroteatment on sulphide catalysts. In 2008, she joined the team of Dr. Duprez to pursue her research interests in the use of biomass for renewable fuels.

Laurence VIVIER

Sebastien Royer obtained his PhD in Chemical Engineering in 2004 from the Laval University, Quebec. His research focused on the catalytic properties of nanocrystalline perovskites for oxidation reactions. In 2006 he achieved the position of Associated Professor at LACCO Poitiers. His research focuses on the design of size- and pore-controlled active oxides for applications in environment and energy.

Sebastien Royer

Daniel Duprez obtained his Ph.D. from Nancy Polytechnicum (France). After a two-year stay at the Elf Research Center at Solaize (near Lyon, France), he joined the Laboratoire de Catalyse en Chimie Organique de Poitiers (France) in 1978. He developed several projects on the use of isotopic exchange for measuring oxygen and hydrogen mobilities on supported metal catalysts, with applications in H2 production from biomass resources, H2 purification, oxidation, and DeNOx reactions and water purification processes (CWAO). Rare-earth oxides are frequently used in these catalytic applications, either alone or as “active” supports of metals.
