Abstract—In this work, a series of heterojunction composites including MWO4 (M: Ce, Cu, Co) and tubular-shaped graphitic carbon nitride were synthesized as efficient photocatalysts towards degradation of tetracycline antibiotic under visible light irradiation. The results showed that the hybridization of materials significantly an enhanced the photocatalytic decomposition activity in which removal rates were found as 90%, 88% and 89% for CuWO4/CN, CoWO4/CN and CeWO4/CN compared to that of pure CN (44%) after visible light irradiation for 2 h. Moreover, the photocatalytic hydrogen production rates were significantly enhanced after hybridization of the materials. The enhanced photocatalytic activity of MWO4/CN composites was attributed to the Z-scheme transfer mechanism, which reduced recombination through the identical interaction among the energy bands of materials. Both characterization and photocatalytic performance tests demonstrated that the MWO4/CN composites were successfully prepared with excellent activity and recyclability.
