S‐Scheme Charge Separation Enables Photocarrier‐Regulated Aqueous NH <sub>4</sub> <sup>+</sup> Storage in g‐C <sub>3</sub> N <sub>4</sub> @WO
Aqueous ammonium‐ion (NH 4 + ) batteries are promising for sustainable energy storage, yet their performance is severely constrained by sluggish reaction kinetics. Photo‐assisted strategies offer a compelling route to overcome these limitations; however, single‐semiconductor electrodes suffer from rapid photogen...
