Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>La₂O₃ and MgO nanoparticles (3–4 nm) supported on carbon nanofibers were evaluated as solid base catalysts for the aldol reaction of benzaldehyde and acetone at room temperature. Both catalysts were found to be highly active and selective with respect to 4‐hydroxy‐4‐phenylbutan‐2‐one, thus suppressing the elimination of H₂O, which is a challenge for this reaction. La₂O₃ nanoparticles were more stable towards water, which makes them more applicable than MgO nanoparticles as a solid base catalyst for this reaction.</p> </abstract>
