Ligand-protected and lowered-temperature hydrothermal synthesis of platinum encapsulated in TON zeolite for shape-selective hydrogenation of furfural to furfuryl alcohol

ZSM-22 encapsulating Pt (Pt@ZSM-22) is obtained by adopting a ligand-protected and lowered-temperature hydrothermal synthesis, followed by direct H 2 reduction. The Pt@ZSM-22 exhibits high furfuryl alcohol selectivity in furfural hydrogenation.
