Hydrogen production via photocatalysis was very effective for sustainable green energy. CuS/C3N4 nanocatalysts were developed under laboratory conditions. XRD analysis showed that CuS with a hexagonal shape was produced and doped on the C3N4. TEM images results showed that CuS nanocatalysts were dispersed on the surface of C3N4 exhibiting a spherical type. The photocatalytic yield of the CuS/C3N4 nanocomposite produced under laboratory conditions was evaluated in municipal wastewaters based on chemical oxygen demand (COD)l as electron donor as a scavenger for H2 production under solar light. The photocatalytic activity for H2 production was promoted by increasing CuS contents from 1% up to 12%. The maximum H2 gas productions was 99% at a CuS/C3N4 nanocatalyst concentration of 4 mgl at a CuS percentage of 12% after 60 minutes photooxidation at a COD concentration of 980 mg/l. With the increase the loading of CuS percentage to 12% the produced nanocomposite indicated stability through visible light irradiation.
