Abstract

CaAl₂O₄:(Eu, Nd)/TiO_2-xN_y composite luminescent photocatalyst was successfully synthesized by a simple planetary ball milling process. Improvement of photocatalytic deNOx ability of TiO_2-xN_y, together with the persistent photocatalytic activity for the decomposition of NO after turning off the light were realized, by coupling TiO_2-xN_y with long afterglow phosphor, CaAl₂O₄:(Eu, Nd). The novel persistent photocatalytic behavior was related to the overlap between the absorption wavelength of TiO_2-xN_y and the emission wavelength of the CaAl₂O₄:(Eu, Nd). It was found that CaAl₂O₄:(Eu, Nd)/TiO_2-xN_y composites provided the luminescence to persist photocatalytic reaction for more than 3 h after turning off the light.
