摘要
以可再生、廉价、天然多孔的锯末和锰源化合物为主要原料,采用浸渍-煅烧法成功地合成了棒状α-MnO2。借助X-射线衍射(XRD)、透射电镜(TEM)、循环伏安以及恒流充放电等测试技术对产物性能进行了系统表征,测试结果表明所得样品为棒状α-MnO2,在1 mol.L-1Na2SO4电解液中,显示出一定的电容特性。
In this paper,rod-like α-MnO2 was successfully synthesized by immersing-annealing technique with the reproducible,low-cost,porous scobs and manganese compound as raw materials.The obtained sample was characterized using various analytical techniques such as X-ray diffraction（XRD）,transmission electron microscopy（TEM）,cyclic voltammetry（CV） and galvanostatic charge and discharge experiments.The results revealed that the as-made sample was rod-like α-MnO2 and had capcitive characteristics in 1.0 mol·L^-1 Na2SO4 electrolyte.
