| 摘 要： | 该文以可再生、廉价、天然多孔的锯末为模板,采用化学溶液浸渍法合成了MnO2纳米棒.TEM,FTIR,XRD测试结果表明,所得样品为α-MnO2纳米棒,其平均直径为15 nm左右,平均长度约为150 nm.循环伏安和恒流充放电测试结果表明:在1.0 mol?L-1的(NH4)2SO4电解液中,0～1.0 V(vs.SCE)电位区间内,充放电的电流密度分别为1 A?g-1和2 A?g-1时,所制备的α-MnO2的最高放电比电容分别达到了176 F?g-1和138 F?g-1.

| Abstract: | In this paper,α-MnO2 nanorods were successfully synthesized via an immersion method by using the reproducible,low-cost,porous sawdust as template.The results of fourier transform infrared spectrum(FTIR),X-ray diffraction(XRD) and transmission electron microscope(TEM) tests showed that the sample was α-MnO2 nanorods with average diameter of 15 nm and with lengths up to 150 nm.The cyclic voltammetry and galvanostatic charge/discharge measurements indicated that the maximum specific capacitance of 176 F·g-1 and 138 F·g-1 were obtained from the synthesized α-MnO2 at the current density of 1 A·g-1 and 2 A·g-1 respectively in a 1.0 mol·L-1(NH4)2SO4 electrolyte between 0 ～1.0 V(vs.SCE). |
