Summary: | Covalent organic frameworks (COFs), an emerging class of framework materials linked by covalent bonds, hold potential for various applications such as efficient electrocatalysts, photovoltaics, and sensors. To rationally design COF‐based electrocatalysts for oxygen reduction and evolution reactions in fuel cells and metal‐air batteries, activity descriptors, derived from orbital energy and bonding structures, are identified with the first‐principle calculations for the COFs, which correlate COF structures with their catalytic activities. The calculations also predict that alkaline‐earth metal‐porphyrin COFs could catalyze the direct production of H2O2, a green oxidizer and an energy carrier. These predictions are supported by experimental data, and the design principles derived from the descriptors provide an approach for rational design of new electrocatalysts for both clean energy conversion and green oxidizer production.
