| 1 | Ribbon-like Cu doped V6O13 as Cathode Material for High-performance Lithium Ion Batteries显示文摘Ribbon-like Cu doped V_6O_(13) was synthesized via a simple solvothermal approach followed by heat treatment in air.As an cathode material for lithium ion battery,the ribbon-like Cu doped V_6O_(13 )electrode exhibited good capacity retention with a reversible capacity of over 313 m Ah?g^(-1) for up to 50 cycles at 0.1C,as well as a high charge capacity of 306 m Ah?g^(-1) at a high current rate of 1 C,in comparison to undoped V_6O_(13 )electrode(267 m Ah?g^(-1) at 0.1C and 273 m Ah?g^(-1) at 1 C).The high rate capability and better cycleability of the doped electrode can be attributed to the influence of the Cu ions on the mophology and the electronic conductivity of V_6O_(13) during the lithiation and delithiation process. | 何金云 龙飞 PENG Daijiang WU Xiaoli MO Shuyi ZOU Zhengguang | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，6： | 3 |
| 2 | Mass Production of Bi3NbO7/Bi2Zn(2/3)Nb(4/3)O7 Composites and Their Visible-light Photocatalytic Activity显示文摘Series Bi_3NbO_7/Bi_2Zn_(2/3)Nb_(4/3)O_7 (BN/BZN) composites were synthesized through a facile solid state reaction method. The products were characterized by X-ray diffraction(XRD), field emission scanning electron microscopy(FE-SEM) and UV-vis diffuse reflectance spectroscopy(DRS). When BN: BZN=0.1 mole ratio, the BN/BZN composite showed the best visible-light-driven photocatalytic performance, which decomposed nearly 100% of Rh B(10 ppm, p H=3-4) within 40 min. The results demonstrated that in-situ solid state synthesis of BN/BZN composites could be an efficient strategy to develop new photocatalyst for environmental remediation. | 彭代江 ZOU Zhengguang HE Jinyun 龙飞 MO Shuyi ZHOU Huanfu | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，2： | 0 |
