•Controlled-synthesized of SnO2 double-shelled and triple-shelled hollow spheres.•SnO2 multi-shelled hollow spheres have good dispersion and uniform sizes.•Photocatalytic properties of double-shelled and triple-shelled hollow spheres.
SnO2 double-shelled and triple-shelled hollow spheres were tailored by adjusting concentration of tin (IV) chloride solution during the process of the tin (IV) ions infused carbonaceous spheres. The structures of these SnO2 multi-shelled hollow spheres were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and their possible formation mechanism were also discussed. In virtue of triple-shelled hollow porous structure and higher specific surface area, SnO2 triple-shelled hollow spheres exhibited enhanced photocatalytic properties compared to SnO2 double-shelled hollow spheres.
