Abstract |
Titanium dioxide (TiO2) has been extensively used on photocatalyst applications, because it has relatively high photocatalytic actively, robust chemical stability, unexpensive and nontoxicity. However, TiO2 has an energy band gap of about 3.2 eV due to the reason it mainly absorbs the ultraviolet portion of the solar spectrum and only a small amount of visible light. Thus, increasing photocatalytic efficiency by increasing light absorption ability of TiO2 is necessary.
In this study, Ce3+, Er3+ and Yb3+ ions were doped simultaneously to TiO2 for expanding light absorption range of TiO2. The effects of synthetic temperatures, concentration of dopants in synthesis process of TiO2 nanoparticles on photocatalytic efficiency for Rhodamine B were investigated. In addition, pH value of photodegradation medium was also optimized. |
