Abstract

The visible light induced photocatalyst SrTi_1 − xCr_yO₃ was synthesized by microwave-assisted solvothermal reaction, followed by coupling with CaAl₂O₄:(Eu,Nd) via mild planetary ball milling. The photocatalytic activities of the SrTi_1 − xCr_yO₃-based composites in the oxidative destruction of NO under solar light were investigated. The results show that CaAl₂O₄:(Eu,Nd)/SrTi_1-xO₃Cr_y composites exhibit prolonged photocatalytic activity for the persistent destruction of NO even after turning off light for 180 min.
