An effective active heterostructured photocatalyst of porous SnO(2)-pillared tetratitanate nanocomposite is synthesized by assembling tetratitanate nanosheets with SnO(2) nanoparticles via an exfoliation-restacking route. The nanocomposite was characterized by powder X-ray diffraction, high-resolution transmission electron microscope, thermogravimetric analysis, UV-vis DRS, X-ray photoelectron spectroscopy, and N(2) adsorption-desorption measurements. It was found that the pillared nanaocomposite is mesoporous with a gallery height of about 2 nm and a specific surface area of 154 m(2)/g.

Fe-doped cesium titanate was obtained by a solid state reaction with a mixture of Cs(2)CO(3), TiO(2), and Fe(2)O(3). ZnO-pillared doped titanate nanocomposite was successfully fabricated by exfoliating doped titanate and restacking its nanosheets with ZnO nanoparticles. The resulting nanocomposite was characterized by powder X-ray diffraction, scanning electron microscope, X-ray photoelectron spectroscopy, N(2) adsorption-desorption measurement, thermogravimetric analysis and UV-vis spectroscopy.

Lithium intercalated tungsten disulfide Li(x)WS(2) with x>1 was solvothermally obtained. It was revealed that Li(x)WS(2) can remain mostly unchanged under vacuum (about 4 kPa) for 5 days. The pH dependences of surface zeta potential for single molecular layers of WS(2) were determined, illustrating that its isoeletric point is approximately at pH 3.

The structure of [Co(H(2)O)(4)][VO(PO(4))](2) is composed of [VO(PO(4))] layers and interlayer tetrahydrated Co(2+) ions. Alternating VO(5) square pyramids and PO(4) tetrahedra share O-atom vertices, thus forming the vanadyl phosphate layers. Two vanadyl oxo groups from neighbouring layers are coordinated to each Co atom in a trans fashion, with Co-O distances of 2.

Each pair of cobalt sites forms a binuclear edge-sharing unit through a (Co(2)O(2)) interaction. The binuclear octahedral units are interconnected through the bridging MoO(4) tetrahedra into a layer structure.
