Cu-In-Zn-S nanoporous spheres for highly efficient visible-light-driven photocatalytic hydrogen evolution

Cu-In-Zn-S (CIZS) nanoporous spheres were prepared by using a facile room temperature method. The band gaps of the CIZS spheres could be tuned by changing the amount of Cu doped. The obtained CIZS nanoporous spheres exhibited excellent photocatalytic activity for hydrogen production from water under visible light irradiation without any co-catalysts.
