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.
Nouveau produit catalytique contenant des composés de titane avec calcaire intégré. Ce produit s'obtient en faisant réagir du calcaire avec un précurseur approprié de dioxyde de titane dans une solution basique, avec extraction du produite dans des conditions particulières, séchage et calcination.En présence de soude, ces opérations permettent d'obtenir un composite sensiblement exempt de dioxyde de titane et contenant du calcaire et du calcium titanate. Utilisé tel quel ou mélangé à d'autre composants, ce composite s'est révélé posséder une activité photocatalytique étonnamment élevée.
