Orthorhombic Limno2

Pure-phase and aluminum-doped orthorhombic LiMnO2 (o-LiMnO2) samples of high discharge capacity and cyclic stability are prepared by a simple one-step hydrothermal reaction with low Li/Mn molar ratio. Mixing LiMn2O4 and doping aluminum improve the electrochemical performance of o-LiMnO2.

Core Shell Structure

The core–shell structure greatly suppressed the shuttle effect of the lithium–selenium battery and the robust carbon shells could remain unbroken even after 100 cycles and flexibly accommodate to the volume change of selenium cores.

Nonaqueous Synthesis

Pure phase TiO2nanomaterials were synthesized by an autoclaving treatment of TiCl4with butanol as a single alcohol source. It was found that the control of molar ratio of TiCl4to butanol played an important role in determining the TiO2crystal phase and morphology. A high molar ratio of TiCl4to butanol favored the formation of anatase nanoparticles, whereas rutile nanorods were selectively obtained at a low molar ratio of TiCl4to butanol. Evaluation of the photocatalytic activity of the synthesized TiO2was performed in terms of decomposition of organic dye rhodamine B under ultraviolet irradiation. It turned out that the as-synthesized TiO2crystallites possessed higher photocatalytic activities toward bleaching rhodamine B than Degussa P25, benefiting from theirhigh surface area, small crystal size as well as high crystallinity.
