Title
Long afterglow phosphor driven round-the-clock g-C3N4 photocatalyst
Abstract

•A novel Sr2MgSi2O7/g-C3N4 photocatalyst was prepared for the first time.•The best mass ratio of Sr2MgSi2O7 in the composite was confirmed.•The new-type photocatalyst can still remain photocatalytic activity for about 6 h in the darkness.•The photocatalytic activity of new-type photocatalyst is enhanced.

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.
