Photocatalytic Degradation of RhB over Nd3+-Ag3VO4 in Aqueous Suspension
1.Introduction Recently, it has been found that Ag3VO4 with monoclinic structure possesses photocatalytic activity for water splitting and decomposition of organic pollutants under visible light irradiation 1,2. Yet its large-scale application is still limited due to the high electron-hole recombination rate in photocatlytic reaction. Therefore, in order to effectively eliminate the recombination of electron and hole, it is necessary to design method to solve this issue. Surface modification by cocatalysts doping is one of the typical approaches to improve the photocatalytic activity of semiconductors. It has confirmed that the rare earth ions/oxides-doped TiO2 or non-TiO2 catalysts showed the enhancement of photocatalytic activities for water splitting and pollutants degradation 3,4. Therefore, it can be inferred that the loading of proper rare earth ions/oxides as cocatalysts maybe enhance the activities of photocatalysts. In this paper, Nd3+-loaded Ag3VO4 catalysts (Nd3+-Ag3VO4) was prepared through impregnation technique and its photocatalytic performance was tested by RhB dye degradation under visible light irradiation. The relationship between the photocatalytic activity and the structure of the prepared catalyst was discussed.
