Abstract
In this study, the photodepostion of metallic silver was examined by immersing strontium-doped sodium tantalate photocatalysts in aqueous AgNO3 solution. When Ta5+ was doped with Sr2+ through a solid-state reaction, the observed photodeposition rate was enhanced by five times relative to that exhibited by undoped NaTaO3. This ehancement was possibly due to restricted electron–hole recombination caused by the doping. On the other hand, when Na+ was doped with Sr2+ through a hydrothermal reaction, only slight enhancement in the photodepositon rate was observed. [DOI: 10.1380/ejssnt.2015.253]
