Abstract

A stable round-the-clock photocatalyst was prepared for the first time by combining Sr₂MgSi₂O₇: (Eu, Dy) (SMSO) and g-C₃N₄. When the external light source was removed, the new-type photocatalyst still remained photocatalytic activity for about 6 h. Furthermore, the photocatalytic activity was enhanced by combined with SMSO, possibly due to the higher visible-light utilization efficiency and the reduced recombination rate of the photo-generated carriers. The repeated photocatalysis experiment showed that the photocatalytic activity was stable.
