A novel strategy is proposed to introduce platinum into the metal nodes of ZIF-8 by preloading Pt as a dopant in ZnO and then converting it to Pt doped ZIF-8 through a chemical vapor deposition approach. The solvent-free conversion allows Pt dopant to coordinate with organic linkers directly, avoiding the formation of Pt nanoparticles, which is a common issue in many methods. This general synthesis strategy may facilitate the discovery of previously unreported mixed-metal organic frameworks.
We propose a novel strategy to introduce platinum into the metal nodes of ZIF-8 by preloading Pt as a dopant in ZnO (Pt-ZnO) and then convert it to Pt doped ZIF-8 (Pt-ZIF-8) through a chemical vapor deposition (CVD) approach. The solvent-free conversion of Pt-ZnO to Pt-ZIF-8 allows the Pt dopant in ZnO to coordinate with organic linkers directly without the formation of Pt nanoparticles, which is a general issue of many methods. This general synthesis strategy may facilitate the discovery of MMOFs that have not been reported previously.
