Abstract
Delafossite CuFeO2 photocathodes have recently attracted attention for water splitting due to their suitable band gap (∼1.5 eV) and high stability in aqueous media. The preparation of CuFeO2 usually requires long and energy‐intense treatments in an inert atmosphere for the full conversion of spinel CuFe2O4 to delafossite CuFeO2. Herein, we report
