Abstract
New photocatalytic product comprising compounds of titanium integrated with limestone. The product is obtained by reacting limestone with a suitable precursor of titanium dioxide in a basic solution, recovering the product in particular conditions, drying it and calcining it. By operating in presence of sodium, a composite is obtained substantially free from titanium dioxide, containing limestone and calcium titanate. The composite thus obtained, used as such or in mixture with other components, has shown an unexpectedly high photocatalytic activity.
