The problem of obtaining samples of strontium bismuthate is studied in the work, the cation sublattice of which is more than half filled with strontium atoms, to study photocatalytic properties. For this purpose it is proposed to use the solid-phase synthesis method. The existence of a critical concentration of strontium atoms in the cation sublattice, which is 75 %, is established. When this concentration is exceeded, the formation of a crystal lattice of strontium bismuthate is not observed. It is shown that the use of strontium carbonate as a catalyst with 35–40 % can substantially increase the photocatalytic activity of strontium bismuthate.
