| Summary: | In this work, the characteristics of saccharose (sucrose)-modified TiO<sub>2</sub> (C/TiO<sub>2</sub>) photocatalysts obtained using a hydrothermal method at low temperature (100 °C) are presented. The influence of C/TiO<sub>2</sub> on survivability and enzyme activity (catalase and superoxide dismutase) of Gram-negative bacteria <i>Escherichia coli</i> (ATCC 29425) and Gram-positive bacteria <i>Staphylococcus epidermidis</i> (ATCC 49461) under UV-A and artificial solar light (ASL) were examined. The obtained TiO<sub>2</sub>-1%-S-100 photocatalysts were capable of total <i>E. coli</i> and <i>S. epidermidis</i> inactivation under ASL irradiation in less than 1 h. In addition, the impacts of sugars on the photocatalytic activity and disinfection performance are discussed. |
