Abstract

L'invention porte sur des produits cimentaires et des articles manufacturés comprenant du dioxyde de titane dopé par du carbone, ayant une activité photocatalytique de longue durée. Le dioxyde de titane contenu dans ceux-ci peut être obtenu par irradiation de dioxyde de titane dans des conditions spécifiques de longueur d'onde, en présence d'une circulation de gaz comprenant un gaz inerte et un composé organique. Le dioxyde de titane ainsi traité acquiert une teneur en carbone élevée et stable, en conservant sa surface spécifique pratiquement inchangée. Les produits/articles cimentaires manufacturés le contenant ont un effet photocatalytique élevé et efficace.
