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.

“…Recently, we have reported that diols are selectively dehydrated to form unsaturated alcohols over pure CeO 2 : 3-buten-2-ol and 2-buten-1-ol are mainly produced in the dehydration of 1,3-butanediol at 325°C [1][2][3]. The catalytic activity of CeO 2 strongly depends upon its crystal planes: the CeO 2 (111) face catalyzes the dehydration of diols, while the other faces catalyze side reactions, such as dehydrogenation [3][4][5][6][7].…”

The dehydration of 1,3-butanediol was investigated over CeO 2 -ZrO 2 catalysts prepared by impregnation at temperatures of 325-375°C. Pure CeO 2 selectively catalyzed the dehydration of 1,3-butanediol to form 3-buten-2-ol and 2-buten-1-ol, while pure ZrO 2 , which was less active than pure CeO 2 , catalyzed the dehydration to 3-buten-1-ol. In the CeO 2 /ZrO 2 catalyst in which CeO 2 was supported on zirconia, the presence of a small amount of CeO 2 suppressed the formation of 3-buten-1-ol and induced the dehydration of 1,3-butanediol to form 3-buten-2-ol and 2-buten-1-ol and the subsequent dehydrogenation of 3-buten-2-ol to form 3-buten-2-one and butanone. The activity would be related to the redox features of CeO 2 . The monoclinic phase of zirconia support decreased while the cubic CeO 2 phase increased as CeO 2 content was increased. In contrast, in the ZrO 2 /CeO 2 catalyst in which ZrO 2 was supported on cubic CeO 2 , only the cubic CeO 2 phase was observed and ZrO 2 species appeared in the form of a solid solution of CeO 2 -ZrO 2 with fluorite structure. Regardless of zirconia loading, ZrO 2 species did not affect the catalytic activity of ZrO 2 /CeO 2 , which was controlled by CeO 2 species.

“…It's well known that CeO 2 has good redox ability for the capacity of active oxygen vacancies formation and steady-state concentration maintenance of them in some reactions [16]. CeO 2 has preferable activity to that of ZrO 2 for its proper bond strength and excellent redox capability in hydrogenation process [17,18].…”

Deactivation of CeO2 catalyst in the hydrogenation of benzoic acid to benzaldehyde

et al. 2007

View full text Add to dashboard Cite

The CeO 2 catalyst has been investigated for hydrogenation of benzoic acid to benzaldehyde and shows little deactivation in stability test. BET results indicate that no significant sinter was observed on the used catalyst. SEM images show few changes taking place in surface feature of the used catalyst. Element analysis confirms that some coke is formed which leads to catalyst deactivation. XRD analysis reveals that crystalline size of catalyst is not relevant to the catalytic behavior in the range from 14.3 nm to 18.4 nm.
