Zn-Al hydrotalcite with Zn/Al =3 was prepared by coprecipitation. Its crystal, porous and electronic structure has been modified using hydrothermal and mechanochemical treatments. The samples with physicochemical parameters, which varied in wide limits, have been obtained. As a result, compositions, which are zinc oxide dispersed in interlayer space of hydrotalcite, absorb visible light and becomes photocatalytic activity under visible irradiation. |
