Abstract

Hollow spheres of multicomponent (CuIn)xZn2(1−x)S2 solid solutions have been rapidly synthesized by a salt-assisted aerosol decomposition method. (CuIn)0.2Zn1.6S2 hollow spheres with a band gap of 2.53 eV exhibited an excellent and stable photocatalytic activity of 360 μmol h−1 (50 mg photocatalysts) for hydrogen evolution from aqueous solutions containing sacrificial reagents (SO32− and S2−) under visible light (λ ≥ 420 nm) due to the well-crystallized microspheres and mesoporous structures. H2 evolution rate of the (CuIn)0.2Zn1.6S2 hollow spheres reached as high as 57 μmol h−1 (50 mg photocatalysts) even without Ru loading.
