Clean production of chlorine (Cl ₂ ) and hypochlorous acid (HOCl) from photocatalytic and photoelectrochemical seawater splitting

/HOCl serves as a green and sustainable alternative to the chlor-alkali process. This research area is still in its infancy, and we hope that this review article will garner the attention of researchers to contribute to this area, leading to a step closer toward practical applications.
