Bicarbonate-based electrolytes are ubiquitous in aqueous electrochem. CO2 reduction, particularly in heterogeneous catalysis, where they demonstrate improved catalytic performance relative to other buffers. In contrast, the presence of bicarbonate in organic electrolytes and its roles in homogeneous electrocatalysis remain underexplored. Here, the authors study the influence of bicarbonate on Fe porphyrin-catalyzed electrochem. CO2 reduction Bicarbonate is a viable proton donor in organic electrolyte (pKa = 20.8 in DMSO) and urea pendants in the 2nd coordination sphere can be used to template bicarbonate in the vicinity of a mol. Fe porphyrin catalyst. The templated binding of bicarbonate increases its acidity, resulting in a 1500-fold enhancement in catalytic rates relative to unmodified parent Fe porphyrin. This work emphasizes the importance of bicarbonate speciation in wet organic electrolytes and establishes 2nd-sphere bicarbonate templating as a design strategy to harness this adventitious acid and enhance CO2 reduction catalysis.
