Abstract
Highly crystalline hydroxide MgSn(OH)6 (MHS) polyhedral particleswere synthesized by changing reaction time (10, 15 and 20 h) in ahydrothermal process. The structural and morphological poperties ofobtained samples were characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM), and UV-vis diffuse reflectancespectroscopy (DRS). The photocatalytic activity of the MHS wasfurther evaluated by the degradation of methyl orange (MO) underultraviolet (UV) light illumination. Compared with commercial TiO2(Degussa P25), the MHS prepared for 15 h showed similar degradationefficiency of methyl orange (MO), mainly due to its higher specificsurface area (55 m2g−1) and better optical properties.
