The effect of the relative concentration of strontium in the cation sublattice of strontium bismutate on its photocatalytic properties

In present paper issues of obtaining strontium bismuthate samples, which cation sublattice has more then 50% of strontium atoms, for the research of photocatalytic properties are investigated. Solid phase synthesis method is suggested as a method of obtaining samples. Critical concentration 75% of strontium atoms in cation sublattice is discovered. If concentration exceeds 75%, formation of strontium bismuthate crystalline lattice is not observed. Shown that usage 35- 40% of strontium carbonate as a co-catalyst lets significantly increase photocatalytic activity of strontium bismuthate.
