Pt and Ni Nanoparticles Anchored into Metal–Organic Frameworks MIL-101 (Cr) as Swift Catalysts for Ethanol Dehydration

In this study, Pt and Ni nanoparticles were anchored into the metal–organic-framework MIL-101 (Cr), by using rotary chemical evaporation method in the in-situ reduction step. Neat MIL-101 (Cr) as well as Pt/MIL-101 and Ni/MIL-101 were characterized through XRD, FT-IR, DSC/TGA, N2 physisorption and T...

Description
Summary:In this study, Pt and Ni nanoparticles were anchored into the metal–organic-framework MIL-101 (Cr), by using rotary chemical evaporation method in the in-situ reduction step. Neat MIL-101 (Cr) as well as Pt/MIL-101 and Ni/MIL-101 were characterized through XRD, FT-IR, DSC/TGA, N2 physisorption and TEM techniques. The catalytic performances of various catalyst samples were assessed in ethanol conversion using the micro catalytic pulse-flow technique at different operating conditions. The MIL-101, as a member of Cr-MOFs, was revealed as cubo-octahedral crystalline particles of uniform sizes (~212 nm). It exhibited high surface area (2100 m 2 g −1 ) of narrower pore radii (
