Abstract

The N/Cl co-doped TiO2 nanostructures were studied as photocatalyst for rhodamine B (RhB), Methylene Blue (MB), and Methyl Orange (MO) degradation. A Commercial TiO2 (P25) grade was also compared to our materials. The N/Cl co-doped TiO2 at different Ti4+ precursors were synthesized by the co-precipitation method. The structural, surface morphology, and surface area were analyzed by XRD, SEM, TEM, and BET. Optical properties of samples were investigated by UV-visible spectroscopy showing that the N/Cl co-doped TiO2 has smaller bandgap than the P25. Overall, the improved N/Cl co-doped TiO2 samples showed better performance than the P25 for RhB, MB and MO degradations.
