Abstract (en)

[origin: GB2441531A] A mesoporous metal or metal compound is electrochemically deposited from a mixture comprising a first metal compound, a solvent and an ionic surfactant in amounts sufficient to form a liquid crystal phase. The first metal compound is present in the aqueous component of the liquid crystal phase containing mixture at a concentration of at least 0.4 M, which is a concentration where a comparative mixture containing the non-ionic surfactant Brij 56 instead of the ionic surfactant would cause the liquid crystal phase to be unstable or produce a deposit with a cathodic charge density less that half the value obtained using the ionic surfactant at the same deposition charge density. The surfactant may be an amine or ammonium compound, e.g. NR<1>R<2>R<3> or N<+>R<1>R<2>R<3>R<4>X<-> where at least one of R<1> to R<4> is a hydrocarbon group having at least 8 carbon atoms, salts containing long chain fatty acids, hydrocarbon residues with at least 8 carbon atoms, cetyltrimethylammonium chloride, cetyltrimethylammonium bromide, sodium dodecyl sulphate, hexadecyl amine, dodecyltrimethylammonium chloride or dioctyl sodium sulphosuccinate.
