(CuIn)0.2Zn1.6S2 solid solution with hollow structure was fabricated by a simple one-step hydrothermal method.
The formation of (CuIn)0.2Zn1.6S2 hollow structure was based on a bubble template mechanism.
RuSx modified (CuIn)0.2Zn1.6S2 photocatalysts exhibited an apparent quantum yield of 11.5% at 420 nm.
This work demonstrated the important role of sulfur source on the physicochemical and photocatalytic properties of metal sulfide photocatalysts.
