摘要：
TiO2/CoO nanocomposites were prepared by the sol-gel method with and without additives such as carboxymethyl cellulose (CMC), polyvinylpyrrolidone, (PVP), and hydroxypropyl cellulose (HPC). The structures and properties were characterized with FT-IR, XRD, SEM, and EDAX techniques. The photocatalytic activity under UV-irradiation to remove organic pollutants was investigated. The results revealed that additives have a significant effect on the particle size distribution and photocatalytic activity of TiO2/CoO nanocomposites. SEM pictures showed that the particle size of TiO2/CoO powder with additives was smaller than that of samples without any additive.
