Porous hydroxyapatite-TiO2 nanocomposites from natural phosphates and their decolorization properties

Résumé

Titanium dioxide-hydroxyapatite nanopowders were prepared by the simultaneous gelation of a titanium alkoxide and precipitation of a redisolved natural phosphate mineral. Evolution of the crystallinity, porous features and surface reactivity of these powders as a function of Ti content and heating was studied. Optimal conditions were found for the preparation of a low-cost nanocomposite powder that was as effective as pure titania for the decolorization of methylene blue solutions.
