This work focused on the synthesis of high‐activity strontium titanate ( SrTiO 3 ) photocatalysts through an environmentally friendly process. A high energy‐efficient microwave‐assisted hydrothermal method was employed to prepare Fe ‐loaded SrTiO 3 that consisted of small particles around 50 nm in diameter. To achieve the effective assistance of long‐lasting fluorescence, the obtained Fe ‐loaded SrTiO 3 samples were coupled with CaAl 2 O 4 :( Eu , Nd ). The photocatalytic activities were evaluated by the photo‐decomposition of NO . Fe loaded SrTiO 3 showed high photocatalytic activities not only under visible light irradiation but also in the dark with fluorescence assistance.
