Abstract
The most frequently used photoactive composite materials are based on titanium dioxide. These composites are capable to convert solar energy into chemical energy to oxidize or completely mineralize the adjacent molecules. This work is focused on the photocatalytic degradation of microorganisms by the prepared TiO2/SiO2 nanocomposite and on its antibacterial characterization. The intention of this work is the nanocomposite application on the building objects and other available surfaces in order to improve their quality and to reduce deteriorating processes caused by biology pollutants such as algae, lichens, bacterias etc. The photocatalytic material TiO2/SiO2 was prepared. For the antibacterial activity characterization the ISO standard method was used - test method for antimicrobial activity of photocatalytic Semiconducting materials. The antibacterial effect was tested on the bacteria Escherichia coli. We proved the strong antibacterial efficiency of the prepared TiO2/SiO2 composite and its ability to improve building surfaces conditions.
