The copper based nanoparticles was synthesized by glycine-nitrate process (GNP), using copper nitrate trihydrate [Cu(NO 3 ) 2 · 3H 2 O] as main starting materials and glycine [C2H5NO2] as complexant and incendiary agent. The as-prepared powders were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM) techniques. Results of the photocatalytic degradation of Nonylphenol polyethoxylates (NP9EO) in a custom-made photoreactor indicated that the maximum degradation (more than 94% and 70% TOD removal) of NP9EO occurred with CuO+Cu 2 O composite catalyst (dosage of 0.3 g/L) when a combination of ultraviolet (UV) irradiation for 600 min, and a heterogeneous system was used.
