TiO2 Nanocatalysts Supported on a Hybrid Carbon-Covered Alumina Support: Comparison between Visible Light and UV Light Degradation of Rhodamine B
Table 1
Comparison of photodegradation efficiencies of Rhodamine B by free and CCA/TiO2 under UV and visible-light illumination.
| Light source | Catalyst | Degradation efficiency (%) | Time taken (min) |
| Visible light | Photolysis (no catalyst) | 4 | 270 | Visible light | Unsupported TiO2 | 20 | 270 | Visible light | CCA-supported TiO2 | 100 | 180 | UV-visible light | Unsupported TiO2 | 100 | 270 | UV-visible light | CCA-supported TiO2 | 100 | 240 |
