Abstract

Sr₄Al₁₄O₂₅:(Eu, Dy)/TiO _2-xN_y composites were synthesised via the solvothermal reaction followed by the mild ball-milling, and the photocatalytic activities were evaluated for deNO_x ability both under artificial solar irradiation with 69.3 W/m² and after turning off the light. It was confirmed that TiO_2-xN_y nanoparticles with rutile phase could be uniformly dispersed on the surface of Sr₄Al ₁₄O₂₅:(Eu, Dy). The improvement of photocatalytic deNOx ability of TiO_2-xN_y, together with the persistent photocatalytic activity for the decomposition of NO gas after turning off the light was realised.
