Efficient persistent photocatalytic decomposition of nitrogen monoxide over a fluorescence-assisted CaAl2O4:(Eu, Nd)/(Ta, N)-codoped TiO2/Fe2O3

► Compensated codoped TiO2 were prepared by microwave-assisted hydrothermal method. ► The photocatalytic activity was further increased by the interfacial charge transfer. ► CaAl2O4:(Eu, Nd)/(Ta, N)-TiO2/Fe2O3 as a efficient fluorescence-emitting Photocatalyst. ► Degradation of pollutant gas proceeded in a continuous flow system or a closed system. ► Persistent catalytic ability after turning off light in dark was realized.
