Abstract

AgInZn7S9 with a 2.3 eV band gap, which was a solid solution of AgInS2 and ZnS semiconductors, showed photocatalytic activity for H2 evolution from an aqueous solution containing sacrificial reagents SO32- and S2- under visible light irradiation (λ > 420 nm) even without a Pt cocatalyst, and loading of the Pt cocatalyst improved the photocatalytic activity.
