While a variety of methods have been explored for the heterogenization of homogeneous complexes, we here report a novel approach using a hierarchical porous carbon material, derived from a Metal Organic Framework, as a support for the well‐known molecular catalyst [Re(bpy)(CO)3Cl] (bpy = 2,2’‐bipyridine). This cathodic hybrid material, named Re@HPC, has been tested for CO2 electroreduction using a mixture of an ionic liquid (1‐Ethyl‐3‐methylimidazolium tetrafluoroborate, EMIM) and water as the electrolyte. Interestingly, it catalyzes the conversion of CO2 into a mixture of carbon monoxide and formic acid, with a selectivity that depends on the applied potential. The present study thus reveals that Re@HPC is a remarkable catalyst, enjoying excellent activity (turnover numbers for CO2 reduction of 7835 after 2 h at ‐1.95 V vs Fc/Fc+ with a current density of 6 mA cm‐2) and good stability. These results emphasize the advantages of integrating molecular catalysts onto such porous carbon materials for developing novel, stable and efficient, catalysts for CO2 reduction. %G English %2 https://univ-pau.hal.science/hal-02950396/document %2 https://univ-pau.hal.science/hal-02950396/file/DG%20hal-02950396-1.pdf %L hal-02950396 %U https://univ-pau.hal.science/hal-02950396 %~ CNRS %~ CDF %~ UNIV-PAU %~ IPREM %~ LCPB %~ INC-CNRS %~ PSL %~ IPREM-PCM %~ SORBONNE-UNIVERSITE %~ SORBONNE-UNIV %~ SU-SCIENCES %~ TEST-HALCNRS %~ CDF-PSL %~ SU-TI %~ UPPA-OA %~ ALLIANCE-SU %~ CHIMIE-SU
