| Abstract: | A series of complexes of surfactant@polyoxoanions were prepared by water/chloroform two-phase electrostatic encapsulating technology, employing polyoxoanion CeW10O369- with high photocatalytic activity and cationic surfactants in different structure as building blocks. The composition and structure of the complexes were analyzed by Fourier infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The effects of various surfactants, catalyst dosage, concentration of methyl orange, and organic dyes on the photocatalytic degradation rate were investigated, in which methyl orange and surfactant@polyoxoanions complexes were used as photodegradation substrate molecule and photocatalyst, respectively. The photodegradation activities for different composite catalysts of surfac-tant@polyoxoanions are in the order of DTAB (dodecyltrimethylammonium bromide)@CeW10 > TTAB (tetradecyltrimethylammonium bromide)@CeW10 > CTAB (cetyltrimethylammonium bromide)@CeW10 > OTAB (octadecyl trimethyl ammonium bromide)@CeW10 > DODA (dioctadecyl dimethyl ammonium bromide)@CeW10. |
