Abstract

The paper presents results of synthesizing Ag-Cu₂O nanocomposites by one pot method. The characteristics, properties of Ag-Cu₂O nanocomposites were determined by X ray diffraction, Field Emission Scanning Electron Microscopy (FESEM) and UV-Vis diffuse reflectance spectroscopy. The obtained results indicated that the crystalline size of Cu₂O particles was about 38.36 nm while that of Ag particles was about 12 nm. The FESEM images showed tendency of agglomeration of Cu₂O particles. The Ag nanoparticles were dispersed regularly on the surface of Cu₂O particles. Due to modification by AgNO₃salt solution, the Ag-Cu₂O nanocomposites had a better ability to absorb light than the Cu₂O particles and had a lower bandgap energy. Additionally, the Ag-Cu₂O nanocomposites also had a higher photocatalytic activity than that of the Cu₂O particles. The Ag-Cu₂O nanocomposite is promising for water treatment application
