A photocatalytic powder for environmental clarification, comprising finely divided titanium dioxide particles having a coating of porous calcium phosphate formed on at least part of the surface of each titanium dioxide particle, wherein an anionic surface active agent is present at least on the interface between said coating of porous calcium phosphate and the titanium dioxide particle. This photocatalytic powder is produced by dispersing finely divided titanium dioxide particles in an aqueous slurry containing an anionic surface active agent, and then forming a coating of porous calcium phosphate on at least part of the surface of each titanium dioxide particle. This photocatalytic powder is used, for example, by supporting it in an organic polymer shaped article.
Poudre photocatalysante pour la purification de l'environnement, qui comprend des particules fines d'anhydride titanique et une couche d'enrobage poreuses de phosphate de calcium formée sur au moins une partie de la surface des particules, un surfactant anionique étant présent au moins au niveau de l'interface située entre la surface des particules fines d'anhydride titanique et la couche d'enrobage de phosphate de calcium. On produit la poudre photocatalysante en dispersant les particules fines d'anhydride de titane dans une suspension aqueuse contenant un surfactant anionique et en formant ensuite une couche d'enrobage poreuse de phosphate de calcium sur la surface des particules fines. On utilise ladite poudre photocatalysante, par exemple, sur un support polymère organique moulé.
