Abstract
Metal Organic Frameworks (MOFs) have been explored widely to create heterogeneity in a catalytic system. Catalytic applications require the use of stable catalysts with no leaching and easy recovery. In this regard, Pt@MIL-101 is embedded in a poly-є-caprolactone (PCL) matrix by means of electrospinning to create a “catalytic carpet” which is highly efficient and can be recovered within seconds after catalysis. The obtained composite material is completely intact with a homogeneous distribution of the Pt@MIL-101 throughout the electrospun PCL fiber matrix. The catalytic carpet was examined in the hydrogenation of cyclohexene and full conversion was obtained in just 90 min. Remarkably, a very large fraction (>65%) of the total Pt-atoms participate in the reaction. Reusability tests showed that the material could be recycled for at least 4 runs without detectable Cr and Pt leaching displaying the durability of the catalytic carpets. Complete recovery is achieved with zero weight loss while fully preserving the crystalline structure.
