Cocatalyst designing: a binary noble-metal-free cocatalyst system consisting of ZnIn₂S₄ and In(OH)₃ for efficient visible-light photocatalytic water splitting.

ABSTRACT: A binary noble-metal-free cocatalyst consisting of ZnIn₂S₄ and In(OH)₃ was developed via a facile one-step hydrothermal method. The ZnIn₂S₄/In(OH)₃ modified ZnWO₄ nanocomposite exhibited enhanced photocatalytic H₂ evolution activity compared to all the related pure samples and binary composite photocatalysts under visible light irradiation. The enhanced photocatalytic hydrogen production activities can be attributed to the synergistic effects of the favorable light trapping ability and efficient spatial charge separation. The photocatalytic hydrogen evolution activity over other semiconductors, such as Zn₂SnO₄ and TiO₂, can also be significantly increased by loadi
