Activity and stability of mesoporous CeO2 and ZrO2 catalysts for the self-condensation of cyclopentanone

[Display omitted] •Mesoporous oxides were synthesized by soft-templated method for cyclopentanone aldol condensation.•α-H abstraction from cyclopentanone to form the enolate is the rate-limiting step.•meso-ZrO2 shows high catalytic activity but rapidly deactivates.•The stronger base site on meso-ZrO...
