Novel hybrid nanomaterials were synthesized using microporous metal-organic framework MIL-53(Al) as a support for rhodium nanoparticles (Rh NPs). In order to elucidate the factors that govern the dispersion and location of Rh, MIL-53(Al) samples were synthesized using two alternative strategies: conventional solvothermal procedure and microwave (MW) activation of the reaction mass. It was established that the use of different preparation conditions for the synthesis of the MIL-53(Al) carrier results in the spatial manipulation of the structural characteristics of the Rh@MIL-53(Al) nanohybrids. The structural study revealed also a pronounced confinement effect of the MIL-53(Al) porous matrix for the Rh nanoparticles. The novel Rh@MIL-53(Al) nanohybrids show high efficiency in “green” ethylene hydroformylation into propionic aldehyde (propanal) using syngas produced by CO2 hydrogenation. Carbon dioxide hydrogenation (atmospheric pressure, 500oC) was performed over cobalt nanoparticles deposited on the MIL-53(Al) nanomaterial obtained in MW fields. Exceptionally high thermal stability of the MIL-53(Al) matrix under conditions of the two-stage catalytic process was found. This work results demonstrate the new potential of the nanostructured catalysts based on the MIL-53(Al) carrier in the carbon dioxide conversion into value-added products.
