Structure-Thermochemistry-Activity Relationships of MOF-based Electrocatalysts
The adsorption energy of catalytically relevant intermediates lays the foundation of heterogeneous catalyst design principles as it correlates with the reaction rate. Yet, the exact interfacial structure of conventional heterogeneous catalysts remains ambiguous. This further hampers an understanding of how the catalyst structure and the surrounding environment can be tailored for optimal performance. Using the structural explicitness and modularity of MOFs to our advantage, our group uses redox active MOFs as candidate electrocatalysts to directly measure catalytically relevant binding energies. Systematic modulation of the local and the extended lattice structure will assess how these can be harnessed to our advantage in yielding optimal binding energy, and therefore high catalytic performance.
