Description
Summary:Layered composites, Zr-intercalated MoS 2 , have been prepared utilizing the exfoliation and restacking properties of Li x MoS 2 under mild conditions and characterized by X-ray powder diffraction, differential scanning calorimetry and BET surface measurements. It showed the formation of two distinct products depending on the employed Zr:MoS 2 reaction stoichiometry. The interlayer expansions of about 4.4 Å and 9.2 Å suggested mono- or bi-layer arrangements of the hydroxyl–Zr oligocations into the interlayer galleries between the MoS 2 host layers. The composites exhibit good catalytic activities in the hydrogenation of nitrobenzene into aniline, due to their intercalated structures and great specific surface areas.
