Abstract The hollow 3D SnS2 hierarchical microcubes (H-SnS2) constructed by 2D nanoflake subunits were synthesized via a topotactic transformation of co-precipitated hollow ZnSn(OH)6 microcubes (H-ZnSn(OH)6) through hydrothermal treatment. In addition, H-ZnSn(OH)6 not only are used as a reaction reagent but also play a key role as sacrificial template. The morphology and structure of the as-prepared products were well characterized by XRD, FESEM, TEM and HRTEM. Employing a structural optimized technique, the photocurrent density of H-SnS2 of up to 1.4 μA cm−2 at 1.23 V (vs. RHE) under simulated solar light irradiation has been achieved, and this can open a new way to enhance the performance of photoelectrochemical water splitting through the design of new structure.
