The new photocatalysts have been obtained by coupling SrTi_1-xCr_xO_3-y with Sr₄Al₁₄O₂₅:(Eu, Dy). Sr₄Al₁₄O₂₅:(Eu, Dy) with eye-visible persistent luminescence can be used as a light source after a promising coupling. The obtained Sr₄Al₁₄O₂₅:(Eu, Dy)/SrTi_1-xCr_xO_3-y catalysts were found to persistently reduce NO in the dark after turning off the solar light irradiation, while the photocatalytic activity of unsupported SrTi_1-xCr_xO_3-y immediately disappeared.
