• In this work, we report the photocatalytic reuse study of AgCl-xGO composite with different GO concentration (x = 1, 2, 4 and 8 mass %) to degrade cationic dyes. X-ray diffraction and scanning electron microscopy analysis were performed to characterize the formation and morphological features of the synthesized AgCl-xGO composite. Raman spectroscopy and UV–Vis studies were used to characterize the AgCl optical properties. It was observed an Increasing in the photocatalytic efficiency due to interface created by AgCl-GO composite associated to the impeding recombination of the electron–hole pair. Additionally, we notice that after 3 min of exposure to UV radiation, the AgCl-8%GO composite completely degraded the methylene blue dye while pure AgCl sample degraded 75.3%. The AgCl-8%GO composite showed stable photocatalytic activity even after the fourth cycle, indicating a high potential for application in consecutive photocatalytic cycles.
