Zr(IV) basic carbonate complexes as precursors for new materials: synthesis of the zirconium-surfactant mesophase

Soluble anionic carbonate complexes of Zr(IV) are produced by addition of Zr(IV) salts to the excess of an alkali metal or ammonium carbonate. The solutions are metastable at pH 7-10 and can be used as the precursors for the synthesis of new materials, as illustrated by the example of the surfactant containing mesophase with a wormhole-like structure, prepared by means of reaction with cetyltrimethylammonium bromide.
