Co-B合金粉体的制备和电化学行为吕东生1,李伟善1,谭春林1,曾荣华1(1.广东省广州市华南师范大学化学与环境学院)摘 要:通过NaBH4还原CoSO4溶液制备了Co0.68B0.32,Co0.55B0.45和Co0.50B0.50一系列超细非晶态Co-B合金粉体.电化学测试表明,在300 mA/g的高电流密度下,3种合金电极的首次放电容量分别高达510.6,666.4和667.2 mA·h/g,经60次循环后,放电容量仍分别有331.6,379.5和390.5 mA·h/g.3种合金电极还表现出良好的高率放......
Solid oxide membrane-assisted electrolytic reduction of Cr2O3 in molten CaCl2Bo Wang1,2,Chao-yi Chen1,2,Jun-qi Li1,2,Lin-zhu Wang1,2,Yuan-pei Lan1,2,Shi-yu Wang1,21. College of Materials... electrolytic reduction of solid Cr2O3 to Cr in molten CaCl2 was performed using a sintered porous Cr2O3 cathode paired with an yttria-stabilized zirconia(YSZ) tube anode containing carbon-saturated liquid copper......
Synthesis and characterization of novel cathode material Li3V2(PO4)3 by carbon-thermal reduction method ZHONG Sheng-kui(钟胜奎)1,2, YIN Zhou-lan(尹周澜)1, WANG Zhi-xing(王志兴)3; GUO Hua-jun(郭华军)3, LI Xin... was prepared by a carbon-thermal reduction (CTR) process. V2O5, LiOH?H2O, NH4H2PO4 and C were used as starting materials to synthesize Li3V2(PO4)3 by sintering the mixture at 800 ℃ for 24 h. The property......
of Resource and Environment Engineering, East China University of Science and Technology, Shanghai 200237, China) Abstract: The mechanism of the electrochemical reduction of Ti(Ⅳ) (c(K2TiF6)=0.2mol/L) and B... that the electrochemical reduction of Ti(Ⅳ) proceeds in three-step charge transfer, the cathodic process is quasi-reversible. The electrochemical reduction of B(Ⅲ) occurs in one-step charge transfer......
that the decomposition of hydrogen peroxide is based on the simultaneous oxidation and reduction of the surface manganese ions, which suggests that the catalytic activity is closely related with the electrochemical... electrode even catalyzed by Mn2O3, oxygen reduction proceeds through the peroxide pathway where the molecular oxygen is reduced to , followed by further electrochemical reduction or chemical......
