▎ 摘　　要

Ternary Cu2SnS3 (CTS) and Cu2SnSe3 (CTSe) quantum dots were grown in-situ on reduced graphene oxide (rGO) nanosheets by a facile one-pot colloidal synthesis. Possessing abundant active sites and having the ability to harvest solar energy and to facilitate charge separation, the CTS(e)/rGO 0D/2D nanocomposites showed remarkably enhanced photocatalytic activities for degradation of rhodamine B and methyl orange aqueous solutions upon visible light irradiation. The nanocomposites of rGO supported monodispersed quantum dots were proved to be a suitable platform for photocatalytic applications due to the well-maintained 0D/2D nanostructure [GRAPHICS]
