Versuchsvorschrift

0.05 mol of tetramethylammonium hydroxide (N(CH3)4OH) in aqueous solution was mixed with 0.15 mol of orthophosphoric acid (H3PO4). Then 0.05 mol of titanium dioxide in the anatase form (i.e., native TiO2) was added to the reaction mixture. After thorough mixing, the mixture was sealed inside a pressure reactor at 6~7 atm and heated in an oven at 180° C. for three days. After cooling, rinsing, filtration, and drying, a tetramethylammonium form of layered titanium phosphate (NMe4TP) was obtained.
