Photocatalytic and antibacterial properties of titanium dioxide flat film

Today, one of the biggest problems of humanity is the inadequate access to clean water. For this reason, much effort is devoted to study new effective methods of purifying water, efficiently, at low cost and with less energy. Titanium dioxide (TiO2) plays a central role in energy and environmental research. Several methods have been developed for the realization of TiO2 films for developing very efficient photo-catalytic filters for water purification.
