In this paper, we performed a valuable study of Zn2SnO4/SnO2 composites with shape control, in order to change the surface areas and take advantage of the composite materials at the same time. Furthermore, by controlling the amount of NaOH as a base, shape control was possible e.g., cubic, truncated cubic, cuboctahedron and octahedron shapes. These phenomena indicated that the structural transformation originated via a dissolution-recrystallization accompanying the "Ostwald ripening" process. Also, through the BET measurement and directly calculated area values from SEM images, we confirmed that each particle had a different specific surface area. In order to complement for this phenomenon, the photocatalytic efficiency was measured. The photocatalytic activities of the Zn2SnO4/SnO2 composites were evaluated using UV-Vis-NIR absorption spectroscopy through degradation of a methylene blue (MB) solution under UV-light irradiation. As a result, it was indicated that the initial decomposition rate was improved as the specific surface area become wider.
