Abstract:

A catalyst consisting of platinum nanoparticles on a ZIF-8 support(Pt@ZIF-8) was synthesized in a straightforward one-step procedure, by adding a nanostructured platinum sol during the formation of ZIF-8 at room temperature. Pt@ZIF-8 was highly porous and well crystallized. The Pt nanoparticles were well dispersed within the ZIF-8 support. In the hydrogenation of 1,4-butynediol, Pt@ZIF-8 exhibited high activity, excellent selectivity for 1,4-butenediol of greater than 94%, and reusability. The Pt@ZIF-8 catalyst did not require further additives. The favorable catalytic performance was attributed primarily to the modification of the ZIF-8 support by the platinum nanoparticles.
