Why is it important?
We have synthesized hydrotalcite-supported Pt catalysts by a solution chemistry method under mild and environmentally benign conditions. The reduction of the metal precursor, the deposition of Pt NCs and the crystallization of the support were achieved in a one-step green process with no involvement of any toxic reagents. The as-synthesized catalysts were applied for hydrogenation of cinnamaldehyde in neat water and showed high selectivity toward high activity and high selectivity toward unsaturated alcohol.
Perspectives
This study implies that hydrotalcite-supported Pt NCs are highly selective and stable catalysts for hydrogenation of cinnamaldehyde to a desired unsaturated alcohol by an overall green strategy. The hydrogenation products could be easily separated from the solvent by simple extraction, which is a greener and more convenient process than those using organic solvents.
