Titanium oxychloride is formed in a reaction between titanium chloride (TiCl4) and water.
The mixture of tartaric acid and TiOCl2 solution forms a gel on heating on a water bath which decomposes at higher temperatures, > 423 K.
Mesoporous titania with an average pore diameter of 2.6 nm and pure rutile crystalline structural wall were prepared by hydrolysis of TiOCl2 aqueous solution at lower temperature by using octyl phenol polyethylene oxide as template-directing agent.
Yellow cakes of TiO(OH)2 were dissolved with added HCl solution to form a TiOCl2 solution.
The concentration of titanium in the as- preparedTiOCl2 solutionwas 5.27M, and this was used as a stock solution for synthesis of TiO2.
