Synthesis of Pt@MAF-6 as a Steric Effect Catalyst for Selective Hydrogenation of Cinnamaldehyde

Pt@MAF-6 was designed as a highly selective catalyst for cinnamaldehyde hydrogenation. The aperture of Pt@MAF-6 acted to sterically confine cinnamaldehyde, and 94% selectivity to cinnamic alcohol was obtained at a high conversion of 95%. Steric confinement was inefficient in trans-2-pentenal hydrogenation, showing that encapsulating active sites within a commensurate porous support is important for a steric effect catalyst.
