Solar-driven seawater splitting has emerged as a sustainable approach for producing green hydrogen without relying on high-purity water driven by solar irradiation. In this study, TiO2 coated MoS2 nanocomposite photocatalyst (TiO2–MoS2) was successfully synthesized via sol–gel technique, resulting in coated 2D nanosheet MoS2 with nanoparticle TiO2, and forming a Type-II heterojunction (band gap of 3.2 eV for pure TiO2 to 2.76 eV of TiO2–MoS2). Photocatalytic performance was evaluated under simulated solar irradiation utilizing both pure water and natural seawater collected from Mediterranean, Aegean, Marmara, and Black Seas in Türkiye. Hydrogen generation rates (HGRs) were observed as 988.9, 986.0, 966.5, and 942.1 μmol H2.h−1.gcat−1 for the Aegean, Mediterranean, Marmara, and Black Seas, respectively. Compared with pure water, HGRs were approximately seven times higher in photocatalytic seawater splitting. The nanocomposite photocatalyst demonstrated long-term stability, retaining 85% of its initial activity after 11 h of continuous operation, and cycle durability, maintaining 88% of its initial performance after five consecutive cycles. These results clearly demonstrate the novelty and practical feasibility of solar-driven hydrogen generation from natural seawater, highlighting the strong potential of TiO2–MoS2 nanocomposites for scalable, sustainable hydrogen production.
