["Immobilizing platinum (Pt) single atoms on appropriate supports with optimized coordination environments and electronic structures is a promising strategy to address the problem of chlorine corrosion during seawater electrolysis. Herein, Pt single atoms on nickel-vanadium layered double hydroxides (Pt-SA/NiV-LDH) matrix are fabricated for chlorine tolerance hydrogen generation. Due to the strong synergetic electronic interaction between atomically dispersed Pt and the ultrathin NiV LDH matrix, the adsorption/dissociation feature of *H2O, *OH, and *H are optimized as evidenced theoretically. The as-fabricated Pt-SA/NiV-LDH electrode exhibits an exceptional mass activity (i.e., 30.98 times higher) compared to the commercial Pt/C, along with an ultra-high turnover frequency (TOF) value of 9.90 s-1 in alkaline media. Impressively, only 207 mV overpotential is required to yield a current density of 2000 mA cm-2 in an electrolyte solution containing 1 m KOH and 2 M NaCl, indicating its robust resistance to chlorine. Moreover, this kind of material demonstrates remarkably low overpotentials of 130 and 215 mV to attain the industrial-scale current densities of 1000 and 2000 mA cm-2 in alkaline seawater, accompanied by exceptional stability for 500 h working at 500 mA cm-2. This work provides an insightful reference for the production of sustainable green hydrogen through seawater electrolysis.","The self-supported Pt-SA/NiV-LDH nanosheets optimize both the electrochemical surface area and electron/mass transport channels, allowing to slow down the deposition of ions such as Cl-, Ca2+ and Mg2+. The optimized adsorption/dissociation feature of H2O, *OH, and *H enables the catalysts to address remarkable alkaline HER and seawater electrolysis activity at ampere-level current densities. image"]
