Ti3C2 is synthesized through alkaline hydrothermal reaction,and used as support to prepare Ti3C2-Ag3PO4 photocatalysts with different loading amount.The photocatalysts are characterized by means of FT-IR,XRD,SEM and XPS.It is indicated that Ti3C2 prepared through alkali etching method at 240℃ hydrothermal condition presents a layer structure with low etching degree.In addition,there are trace TiO2 in Ti3C2 material,and Ag3PO4 has been supported on the surface of Ti3C2 support.The photocatalytic activity of Ti3C2-Ag3PO4 increases with the higher Ag3PO4 loading amount.The degradation rate of methylene blue by Ti3C2-Ag3PO4-85％can reach 95％when the usage of the catalyst is 0.01 g and the reaction performs 60 min.The presence of heterojunction between Ti3C2 and Ag3PO4 makes the catalyst have strong charge separation ability and excellent photocatalytic performance.
