hydrothermal synthesis characterization formation mechanism and Electrochemical Property of v3o7 h2o single crystal nanobelts
Materials Science and Engineering B-advanced Functional Solid-state Materials, 2010Co-Authors: Yifu Zhang, Xinghai Liu, Guangyong Xie, Chi HuangAbstract:Abstract Single-crystal V 3 O 7 ·H 2 O nanobelts have been successfully synthesized in a large-scale by ethanol reducing of the commercial V 2 O 5 powder via a facile hydrothermal approach, without any templates and surfactants. The as-prepared V 3 O 7 ·H 2 O nanobelts are up to several tens of micrometers in length, about 100 nm in width and about 20 nm in thickness in average, respectively. The “Hydrating–Reducing–Exfoliating–Splitting” (HRES) mechanism was proposed to describe the formation of the V 3 O 7 ·H 2 O nanobelts. In our research progress, it was found that the ratio of EtOH/H 2 O, the reaction time and categories of the reducing agents had significant effects on the morphology and composition of as-obtained products. Furthermore, the Electrochemical properties of V 3 O 7 ·H 2 O nanobelts were preformed and the results revealed that a lithium battery using those nanobelts as the positive electrode exhibited a high initial discharge capacity of 373 mAh/g.

preparation and capacitive Property of manganese oxide nanobelt bundles with birnessite type structure
Journal of Power Sources, 2011Co-Authors: Xiuhua Tang, Zonghuai Liu, Zupei Yang, Zenglin WangAbstract:Abstract One-dimensional manganese oxide nanobelt bundles with layered structure have been synthesized by hydrothermally treating the precursor, K-type layered manganese oxide in a NaOH solution of 6.0 mol L −1 at 150 °C for 30 h. The obtained material is characterized by XRD, SEM, TEM and BET analysis. The manganese oxide nanobelt bundles are more than 50 μm long and 20–50 nm wide, and the specific surface area is about 160 m 2 g −1 . The Electrochemical Property of the synthesized manganese oxide nanobelt bundles has been studied using cyclic voltammetry in a mild aqueous electrolyte. The manganese oxide nanobelt bundle exhibits good capacitive behavior and cycling stability in a neutral electrolyte system, and its initial capacitance value is 268 F g −1 .
