Influence of the Type and Concentration of the Dopant on the Photocatalytic Activity of Strontium Bismuthate Sr2Bi2O5

The paper investigates the optical and photocatalytic properties of strontium bismuthate doped with various rare earth elements. The data presented indicate that the type and concentration of the dopant have different effects on such parameters of a given semiconductor photocatalyst, such as the optical bandgap, absorption in the intrinsic area, and photocatalytic activity. On the basis of the studies carried out, the most promising rare earth elements have been identified and their optimal concentrations have been established for doping alkaline earth metal bismuthates.
