Set of titanate heterogeneous photocatalysis nano tubes includes products of hydrothermal treatment of an anatase suspension in highly alkaline medium

NOVELTY – The set of titanate heterogeneous-photocatalysis nano-tubes has over 100 m2/g surface area, and the composition Na2-X Hxx Ti307 with X varying as a function of the degree of washing as a function of the degree of washing of the material. USE – In industrial chemistry. DETAILED DESCRIPTION – Also claimed is a process making the tubes. The process greatly reduces the toxicity of the medium being treated, and the nano-tubes are easy to remove from the reaction medium. The nano-tubes are obtained by hydrothermal treatment of a suspension of TiO2 (anatase) in highly alkaline medium.
