Synthesis, Characterization and Photocatalytic Activity of CoMoO4/g-C3N4/rGO under Visible Light

In the present paper, the CoMoO4/g-C3N4/rGO photocatalytic composite material was synthesized using the combined calcination and hydrothermal method. The composite material was characterized using X-ray diffraction, Scanning electron microscopy, Energy-dispersive X-ray spectroscopy, and UV−Vis diffuse reflectance spectroscopy. The results showed that the CoMoO4/g-C3N4 composite material had an absorption spectrum shifted to the visible light region compared to each component CoMoO4 and g-C3N4. The catalytic activity of the material was studied through the treatment efficiency of Levofloxacin antibiotic under visible light conditions. The degradation efficiency of Levofloxacin reached 78.58% after 120 minutes of illumination under pH=7, Levofloxacin concentration of 10 ppm and using 0,05 g of material.
