低维纳米材料CuI的制备

Low-dimensional CuI nanomaterials were synthesized in microemulsions containing cyclohexane， Triton X-100， n-pentanol and aqueous solution. The redox reaction took place in this system and the final products CuI were obtained. It′s found that the morphology of CuI could be influenced a great deal by the experimental param-eters such as w₀ (the molar ratio of water to surfactant)， reactant concentration and the aging time. Hexagonal or shuttle-like CuI flakes， nanoparticles and nanofibers could be prepared respectively under certain conditions.

CaSO4纳米棒(线)的微乳法制备与表征

CaSO₄ Nanorods/wires were synthesized in quaternary W/O microemulsion solution containing triton X-100, cyclohexane and n-pentanol. Transmission electron microscopy (TEM) was utilized to characterize the shape and size of products as-prepared, as well as electron diffraction (ED) pattern was obtained for designated nanorods (wires). It is revealed that ω₀ (molar ratio of water to surfactant),reactants concentration and aging time play an important role in the formation of different morphologies and size of synthesized CaSO₄ nanocrystal.
