Abstract

A new visible-light-driven photocatalyst AgIn₅S₈ was prepared by a simple two-step process, which involves the first co-precipitation process at room temperature and subsequently heat-treatment process at 750 °C under pure argon flow protection. The obtained AgIn₅S₈ sample showed high activity for the evolution of hydrogen under visible light irradiation (λ≥420 nm) from aqueous solution containing S^2- and SO₃^2- ions as sacrificial electron donors. It was found that several experimental parameters, such as the concentration of sacrificial reagents and the loading of Pt co-catalyst, play important roles on the evolution rate of H₂ under visible light irradiation.
