抄録

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]
