CTAB作用下纳米复合材料Ag/ZnO-SnO2的制备与光催化降解罗丹明B
Preparation of Ag/ZnO-SnO2 by CTAB-assisted and Photocatalytic Degradation of Rhodamine B
摘要
Abstract
The nano-composite Ag/ZnO-SnO2 under cetyltrimethylammonium bromide (CTAB) was prepared with a molar ratio of Ag, Zn and Sn of 0.1:2:1 by the sol-gel method combined with temperature-programmed treatment. The phase composition, structures and morphologies of the nanocomposite Ag/ZnO-SnO2 (CTAB) were characterized by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), transmission electron microscopy (TEM) , N2 adsorption-desorption tests and scanning electron microscopy assisted X-ray energy dispersive spectroscopy(SEM-EDS). The results show that the nanocomposite Ag/ZnO-SnO2 is well wurtzite and rutile structures, and Ag in the nano-composite Ag/ZnO-SnO2 is metallic Ag°. Compared with no CTAB-assisted nanocomposite, the nanocomposite Ag/ZnO-SnO2 ( CTAB ) has uniformly distribution and shows regularly nano-rods. By the photocatalytic degradation of RhB, under UV and visble light irradiation, the photocatalytic activity of Ag/ZnO-SnO2 under CTAB-assisted is enhanced, of which is higher than that of Ag/ZnO-SnO2, ZnO-SnO2, ZnO and Degussa P-25.关键词
