Mesolamellar molybdenum sulfides with intercalated cetyltrimethylammonium cations

Two mesolamellar molybdenum sulfides (designated MoS-L-A and MoS-L-B) with intercalated cetyltrimethylammonium surfactant cations have been prepared a t room temperature and under mild hydrothermal conditions, respectively. Po wder X-ray diffraction and transmission electron microscopy reveal that the materials have interlayer distances of 34 and 28 Angstrom. The oxidation s tate of Mo in the compounds is + 4 whereas the sulfur exists as S2-, S-2(-) and S-2(2-) species. The inorganic layers of MoS-L-A and MoS-L-B are compo sed of negatively charged molybdenum sulfide with the negative charges bein g balanced by the cetyltrimethylammonium cations intercalated between the i norganic layers.
