Highly selective hydrogenation of α,β-unsaturated aldehydes by Pt catalysts supported on Fe-based layered double hydroxides and derived mixed metal oxides†
Abstract
The selective hydrogenation of cinnamaldehyde and citral was investigated over platinum catalysts supported on Fe-based layered double hydroxides and derived mixed metal oxides. Among the catalysts, Pt/ZnFe-LDH showed the best activity and selectivity for the hydrogenation of CO bonds in cinnamaldehyde, and citral was mostly transformed into citronellol over the Pt/NiFe-LDH catalyst.
