Nanosized Zn{sub 2}SnO{sub 4} (ZTO) particles were successfully synthesized by a simple hydrothermal process in water/ethylene glycol mixed solution using amines (ethylamine, n-butylamine, n-hexylamine, and n-octylamine) as mineralizer. The products were characterized by X-ray diffractions (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N{sub 2} adsorption. The results indicated that the hydrothermal conditions, such as alkaline concentration (n-butylamine), reaction temperature, solvent composition, and the kind of amines, had an important influence on the composition, crystallinity, and morphology of the product. The as-synthesized ZTO samples exhibited high activities and durabilities for photodegradation of methyl orange and the activities were mainly affected by the crystallinities of the samples. A hexagonal-shaped ZTO (H-ZTO) sample was prepared in 0.53 M of n-butylamine solution at 180 deg. C for 20 h and its optical properties were characterized by UV-Vis diffuse reflectance and Photoluminescence (PL) spectra. Furthermore, the photocatalytic H{sub 2} evolution reaction from ethanol aqueous solution over H-ZTO was also investigated. - Graphical abstract: Nanosized Zn{sub 2}SnO{sub 4} (ZTO) was successfully synthesized by hydrothermal process. Photocatalytic test showed that the samples exhibited high activity and durability for photodegradation of methyl orange (MO) and photocatalytic production H{sub 2} from ethanol aqueous solution.
