The visible light induced photocatalyst SrTi 1-x Cr y O 3 was synthesized by microwave-assisted solvothermal reaction, followed by coupling with CaAl 2 O 4 :(Eu,Nd) via mild planetary ball milling. The photocatalytic activities of the SrTi 1-x Cr y O 3 -based composites in the oxidative destruction of NO under solar light were investigated. The results show that CaAl 2 O 4 :(Eu,Nd)/SrTi 1-x O 3 Cr y composites exhibit prolonged photocatalytic activity for the persistent destruction of NO even after turning off light for 180 min.
