Abstract An efficient approach for fabrication of non‐noble metal‐based electrocatalyst is desirable designing the energy storage and conversion devices in real‐world usages due to low cost excellent catalytic properties. The preparation hollow carbon capsules (HCC) containing cobalt (Co)‐based reported by a simple synthesis process without using templates first time. Initially, phenylphosphonate (Co‐MOF) nanorods are fabricated through hydrothermal approach. as‐formed Co‐MOF covered with thin coating polydopamine (DP‐Co‐MOF) chemical polymerization dopamine Tris‐HCl (pH 8.5). DP‐Co‐MOF used as self‐degraded template formation HCC under pyrolysis. mechanism hydrogen evolution reaction (HER) activity investigated. structure derived N 2 exhibits overpotential (295 mV at 100 mA cm −2 ) stability (90.98%) 150 h, which further verified density functional theory (DFT) calculations. Finally, designed anion exchange membrane (AEM) water electrolyzer based on C─Co─N cathode delivers current 500 (at 2.19 V) 1000 mAcm 2.33 1.0 m KOH 60 °C. new Co‐based highly beneficial cost‐effective high‐performance AEMWEs.
