摘要: Abstract A novel photocatalyst CaSn(OH) 6 with middle-sagged micro-cube morphology was successfully synthesized via a facile sonochemical method. The as-synthesized sample characterized by X-ray diffraction, photoelectron spectroscopy, field emission scanning electron microscopy, transmission UV–vis diffuse reflectance spectroscopy and N 2 absorption–desorption. photoactivity of the evaluated degradation benzene under UV irradiation. results indicated that showed much better photocatalytic activity stability than TiO (P25, Degussa Co.) same conditions. also exhibited high for methyl orange photodegradation. Additionally, possible mechanism photocatalysis over proposed.
