摘要：
The visible light induced photocatalyst SrTi1 - xCryO3 was synthesized by microwave-assisted solvothermal reaction, followed by coupling with CaAl2O4:(Eu,Nd) via mild planetary ball milling. The photocatalytic activities of the SrTi1 - xCryO3-based composites in the oxidative destruction of NO under solar light were investigated. The results show that CaAl2O4:(Eu, Nd)/SrTi1 - xO3Cry composites exhibit prolonged photocatalytic activity for the persistent destruction of NO even after turning off light for 180 min.
