Ultra-long MnOOH nanowire was prepared by a simple hydrothermal process using KMnO4 and ammonium acetate without additional template agents. MnOOH sample was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, amperometry, constant current charge/discharge characterization and electrochemical impedance spectroscopy. The results show that the length of MnOOH nanowires is more than 10 μm, and the diameter is approximately 20 nm. The specific capacitance is 285 F/g at current density of 1 A/g in 1.0 mol/L Na2SO4 electrolyte, and it can still keep a good cycling stability after 4 000 cycles. The post-capacitance retention rate reaches 96.2%. The MnOOH nanowire as an electrode material has an excellent electron transmission channel, exhibiting a superior ultracapacitor performance, which can have broad application prospects as an electrode material for supercapacitors.

以KMnO4和醋酸铵为原料,无需额外的模板剂,采用简单水热法制备超长纳米线状MnOOH,利用X射线衍射仪、扫描电子显微镜、透射电子显微镜、热重分析,循环伏安法、恒流充放电法和电化学阻抗法对合成样品进行表征。结果表明:MnOOH纳米线的长度在10 μm以上,直径约为20 nm,在电流密度为1 A/g时,比电容为285 F/g;在电流密度为10 A/g时,4 000次充放电循环后电容保持率达96.2%;MnOOH纳米线材料可以形成出色的电子传输通道,表现出较为优异的超电容性能,作为超级电容器的电极材料具有广阔的应用前景。

以KMnO4和醋酸铵为原料,无需额外的模板剂,采用简单水热法制备超长纳米线状MnOOH,利用X射线衍射仪、扫描电子显微镜、透射电子显微镜、热重分析,循环伏安法、恒流充放电法和电化学阻抗法对合成样品进行表征。结果表明:MnOOH纳米线的长度在10 μm以上,直径约为20 nm,在电流密度为1 A/g时,比电容为285 F/g;在电流密度为10 A/g时,4 000次充放电循环后电容保持率达96.2%;MnOOH纳米线材料可以形成出色的电子传输通道,表现出较为优异的超电容性能,作为超级电容器的电极材料具有广阔的应用前景。

Ultra-long MnOOH nanowire was prepared by a simple hydrothermal process using KMnO4 and ammonium acetate without additional template agents. MnOOH sample was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, amperometry, constant current charge/discharge characterization and electrochemical impedance spectroscopy. The results show that the length of MnOOH nanowires is more than 10 μm, and the diameter is approximately 20 nm. The specific capacitance is 285 F/g at current density of 1 A/g in 1.0 mol/L Na2SO4 electrolyte, and it can still keep a good cycling stability after 4 000 cycles. The post-capacitance retention rate reaches 96.2%. The MnOOH nanowire as an electrode material has an excellent electron transmission channel, exhibiting a superior ultracapacitor performance, which can have broad application prospects as an electrode material for supercapacitors.
