Abstract

The purpose of this work is the synthesis of Cu2O nanoparticles and its application as photocatalyst. In this work we present a simple and quick method for the production of Cu2O nanoparticles under ambient conditions. We repeated the synthetic route varying different parameters such as time, concentration of reagents etc. The crystal structure of the samples was characterized using X-ray diffraction and the morphology was examined by FESEM, SEM and TEM. We managed to take pure Cu2O with cubic particles 300nm-1800nm. Following the characterization, we checked the stability of the samples in time and temperature. The second step was the research of the different sizes of Cu2O cubes as photocatalysts. As a pollutant we chose three models textile: methyl orange, methylene blue and rhodamine 6G. Initially we noted that only MO can be adsorbed on the surface of particles. In addition we presume that nanoparticles have better adsorption property because of the bigger surface energy. The photocatalytic efficiency of the samples was investigated using visible light
