[Fe]Porphyrin@LDH/LSH Hybrids Materials: Structure, Redox properties and Electrocatalytic behavior towards CO 2 reduction
Résumé
Homogenous electrocatalyst such as iron (III) tetraphenyl porphyrins (FeTPP) show efficient CO 2 transformation. To improve their catalytic durability and enhance the catalytic efficiency, within the framework of the project CALHYCO2-ANR-19-C05-0015, heterogeneous electrocatalysts were prepared by the intercalation of tetrakis-(4-sulfonato-phenyl)-porphyriniron (III) (FeTSPP) in layered double hydroxides (LDH) and layered simple hydroxides (LSH). The structural and morphological characteristics of ZnCr-FeTSPP LDH and Zn-FeTSPP LSH were compared and the electroactivity of the intercalated FeTSPP was studied in different electrolytes in the presence of CO 2 . Preparative-scale electrolyzes were carried out to determine the selectivity and faradic efficiency for the electroconversion of CO2 .
