Organocatalyst Supported by a Single‐Atom Support Accelerates both Electrodes used in the Chlor‐Alkali Industry via Modification of Non‐Covalent Interactions

Abstract Consuming one of the largest amount of electricity, the chlor‐alkali industry supplies basic chemicals for society, which mainly consists of two reactions, hydrogen evolution (HER) and chlorine evolution reaction (CER). Till now, the state‐of‐the‐art catalyst applied in this field is still the dimensional stable anode (DSA), which consumes a large amount of noble metal of Ru and Ir. It is thus necessary to develop new types of catalysts. In this study, an organocatalyst anchored on the single‐atom support (SAS) is put forward. It exhibits high catalytic efficiency towards both HER and CER with an overpotential of 21 mV and 20 mV at 10 mA cm −2 . With this catalyst on both electrodes, the energy consumption is cut down by 1.2 % compared with the commercial system under industrial conditions. Based on this novel catalyst and the high activity, the mechanism of modifying non‐covalent interaction is demonstrated to be reliable for the catalyst's design. This work not only provides efficient catalysts for the chlor‐alkali industry but also points out that the SACs can also act as support, providing new twists for the development of SACs and organic molecules in the next step.
