“…However, when too much precipitate is produced at one time, light cannot fully penetrate, resulting in fewer materials being exposed to light and reducing hydrogen production efficiency. Table ,− shows a comparison of the photocatalytic hydrogen production efficiency (0.003–1.803 mmol h –1 g –1 ) by different nanostructures. In 2 S 3 /In 2 O 3 /Au NCs demonstrate an optimal efficiency even under a low power irradiation intensity.…”

Photocatalytic water splitting under visible light represents a promising pathway toward achieving future net zeroemission renewable energy. However, the development of this energy source faces a challenge owing to the scarcity of freshwater resources. The direct application of actual seawater in photocatalytic hydrogen generation is scarce. This study reports a simple and rapid microwaveassisted synthesis to fabricate a ternary indium sulfide/indium oxide/ gold (In 2 S 3 /In 2 O 3 /Au) nanocomposite photocatalyst. The microwave-assisted synthesis can be performed with precise temperature control in less time. Binary In 2 S 3 /In 2 O 3 nanosheets were first synthesized via a one-pot microwave-assisted synthesis, which exhibited an efficient spatial separation of electrons and holes than individual In 2 S 3 or In 2 O 3 . The incorporation of Au nanoparticles onto nanosheets enhanced visible light absorption and decreased electron−hole pair recombination. In 2 S 3 /In 2 O 3 /Au nanocomposites demonstrated remarkable effectiveness in seawater splitting to generate hydrogen with a high hydrogen evolution rate (1.604 mmol h −1 g −1 ) under low power (5 W blue light and a maximum absorption wavelength of 420 nm) visible light irradiation and low carbon emission for sustainability in water splitting materials. This work has achieved an excellent solar-to-hydrogen conversion efficiency and apparent quantum efficiency of ∼2.11% and ∼5.06%, respectively. The ternary nanocomposites show a high degree of reusability under repeated testing cycles, suggesting their potential and practical application for sustainable hydrogen production in the seawater environment.
