摘要：

This Paper reports the photocatalytic activity of g-C3N4/NaTaO3 hybrid composite photocatalysts synthesized by ball-mill method. The g-C3N4 and NaTaO3 were individually prepared by Solid state reaction and microwave hydrothermal process, respectively. The g-C3N4/NaTaO3 composite showed the enhanced photocatalytic activity for degradation of rhodamine B dye (Rh. B) under simulated solar light irradiation. The results revealed that the band-gap energy absorption edge of hybrid composite samples was shifted to a longer wavelength as compared to NaTaO3 and the 50 wt% g-C3N4/NaTaO3 hybrid composite exhibited the highest percentage (99.6%) of degradation of Rh. B and the highest reaction rate constant (0.013 min(-1)) in 4 h which could be attributed to the enhanced absorption of the hybrid composite photocatalyst in the UV-Vis region. Hence, these results suggest that the g-C3N4/NaTaO3 hybrid composite exhibits enhanced photocatalytic activity for the degradation of rhodamine B under simulated solar light irradiation in comparison to the commercial NaTaO3.
