Facial mixing preception method was used to prepare the CdMoO4/CNTs/g-C3N4. The novel Z-scheme samples were characterized by using XRD, SEM, FT-IR, XPS, UV-vis, PL, EIS and photocurrent response. The photocatalytic activity of the catalyst was measured by degradation of tetracycline hydrochloride (TCH) under visible light. The optimal photocatalytic degradation efficiency of 10 wt% CdMoO4/CNTs/g-C3N4 was up to 85.3%, which was higher than CdMoO4, CdMoO4/CNTs and g-C3N4. The enhanced photocatalytic performance of the heterojunction was attributed to the highly separation efficiency of photogenerated electron-hole pairs. A Z-scheme system was produced in CdMoO4/CNTs/g-C3N4 with the doping of CNTs.
