CONFI-Cat develops the design and the elaboration of innovative hybrid catalysts for selective and stable CO2 electroreduction. The reactivity and stability of the molecular catalysts are controlled by encapsulation. Molecular cages are used as matrices to structure, modify and control the local environment of the molecular electrocatalysts. Mechanistic studies, aimed at identifying the factors governing catalytic activity and selectivity, will complement the experimental developments. The final objective of the project is to develop innovative breathing electrodes based on carbon nanomaterials and cage/electrocatalyst composites for the efficient electroreduction of CO2.
