A growth of SnO2–ZnS heterostructure was realized by a rational two-step thermal evaporation method. Starting with Sn powder, the SnO2 bicrystalline nanoribbons were grown on the silicon wafers. The secondary growth of ZnS on the former SnO2 nanostructures correspondingly resulted in the SnO2–ZnS nanocomb structures. We investigated the morphology, detailed structure by X-ray diffraction (XRD), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). It revealed that the ZnS nanobranches with [001] growth direction are epitaxial grown from the (− 101) crystal plane of the SnO2 trunks with a good lattice match. The nanocomb exhibited an effective photocatalytic activity.
