Abstract This paper describes a promising photoelectrochemical electrode based on a flower‐like Cu 2 In 2 ZnS 5 structure composed of nanosheets and its use as a photoelectrode for photoelectrochemical (PEC) water splitting for the first time. The detailed growth of Cu 2 In 2 ZnS 5 was discussed. The morphology and microstructure were characterized in detail. PEC measurements showed that on the basis of the optimal hydrothermal time, flower‐like Cu 2 In 2 ZnS 5 exhibited high photoelectrochemical activity, as the photocurrent density reached up to 2.00 mA cm −2 . The remarkable PEC performance stems from crucial factors, including improved light absorption, an ideal band gap value, decoupling of the directions of light absorption and charge‐carrier collection, and large surface area. Our results indicate that the flower‐like Cu 2 In 2 ZnS 5 structure composed of nanosheets has enormous potential in PEC water splitting.
