摘要

研究了沉淀氧化锡与银的机械化学和声化学掺杂。采用XRD、SEM、EDS、XPS、吸附氮、TEM、UV-Vis光谱对所得样品进行了表征。掺杂样品具有发达的多孔结构、更窄的带隙和更强的可见光吸收,因此在可见光作用下光降解罗丹明B、红花红T和甲基橙具有较高的光催化活性。

Influence of Doping with Silver on Photocatalytic Properties of Tin Dioxide
Mechano- and sonochemical doping of precipitated SnO2 with silver have been studied. All obtained samples have been investigated using XRD, SEM and EDS, XPS, adsorption of nitrogen, TEM, UV-Vis spectroscopy. The doped samples have a developed porous structure, narrower band gap and stronger absorption of visible light and, as a consequence, high photocatalytic activity in the photodegradation of rhodamine B, safranin T and methyl orange under the action of visible light.
