Key words

rhodium catalysis - hydroformylation - single-atom catalyst - styrenes

Significance

A rhodium single-atom catalyst on CeO2 (Rh1/CeO2) was prepared by mixing RhCl3 and CeO2 in deionized water, followed by calcination at 400 °C (eq. 1). Rh1/CeO2 catalyzed the hydroformylation of styrene derivatives with hydrogen generated in situ from water and carbon monoxide to give the corresponding linear aldehydes in ≤ 99% conversion (eq. 2).

Comment

Rh1/CeO2was characterized by means of ICP-OES, STEM, HAADF-STEM, FT-IR, EDS analyses. In the hydroformylation of styrene, Rh nanoparticles supported on CeO2 (NP-Rh/CeO2) gave 3-phenylpropan-1-ol rather than 3-phenylpropanal, with 99% selectivity (eq. 3).
