TITANIUM AQUO-OXO CHLORIDE AND PREPARATION METHOD THEREOF

摘要

The invention relates to a titanium aquo-oxo chloride and to a method of preparing same. The inventive compound takes the form of crystals and has the following mass composition: Ti 26.91 %, Cl 21.36 %, H 4.41 %, which corresponds to formula [Ti8O12 (H2O) 24] Cl8 HCl 7H2O. The preparation method consists in hydrolysing TiOCl2 either in an atmosphere having a moisture content which is maintained between 50 and 60 %, or by an alkaline carbonate A2CO3, in order to obtain a titanium aquo-oxo chloride. The compound can be used as a semi-conductor element for a photovoltaic cell or as a photocatalyst in air- or water-purification treatment processes.
