Abstract

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.
