Abstract
Nouveau produit catalytique contenant des composés de titane avec du calcaire intégré. Ce produit s'obtient en faisant réagir du calcaire avec un précurseur approprié du dioxyde de titane dans une solution basique, suivi d'un lavage approfondi du mélange ainsi obtenu, d'un séchage et d'une calcination. Le composite obtenu contient du calcaire, du dioxyde de titane et du calcium titanate. Utilisé tel quel ou mélangé à d'autres composants, ce composite s'est révélé posséder une activité photocatalytique étonnamment élevée.
