An iridium pincer dihydride catalyst was immobilized on carbon nanotube‐coated gas diffusion electrodes (GDEs) by using a non‐covalent binding strategy. The as‐prepared GDEs are efficient, selective, durable, gas permeable electrodes for electrocatalytic reduction of CO 2 to formate. High turnover numbers (ca. 54 000) and turnover frequencies (ca. 15 s −1 ) were enabled by the novel electrode architecture in aqueous solutions saturated in CO 2 with added HCO 3 − .
