Abstract

The selective hydrogenation of α,β-unsaturated aldehydes to unsaturated alcohols can reach high selectivity and activity at room temperature using Pt nanoparticles immobilized on a non-porous Al₂O₃ support stabilized by aspartic acid. Aspartic acid molecules had a significant steric effect on C[double bond, length as m-dash]C hydrogenation and could modify the electronic state of metal particles.
