要旨

A simple and scalable method for synthesizing Co₃O₄ nanoparticles supported on the framework of mesoporous carbon (MC) was developed. Benefiting from an ion-exchange process during the preparation, the cobalt precursor is introduced into a mesostructured polymer framework that results in Co₃O₄ nanoparticles (ca. 3 nm) supported on MC (Co₃O₄/MC) with narrow particle size distribution and homogeneous dispersion after simple reduction/pyrolysis and mild oxidation steps. The as-obtained Co₃O₄/MC is a highly efficient catalyst for transfer hydrogenation of α,β-unsaturated aldehydes. Selectivities towards unsaturated alcohols are always higher than 95 % at full conversion. In addition, the Co₃O₄/MC shows high stability under the reaction conditions, it can be recycled at least six times without loss of activity.
