Herein, a hydrogen‐bonded cobalt porphyrin framework is presented that can efficiently host iodine and serve as an electrocatalyst for aqueous zinc‐iodine (Zn‐I2) organic batteries. The Fourier Transform infrared spectroscopy (FT‐IR), X‐ray Photoelectron Spectroscopy (XPS), and Density functional th...
