摘要/Abstract

摘要： 应用化学共沉淀法制备掺钌氢氧化钴复合材料,X射线衍射(XRD)、扫描电子显微镜(SEM)显示非晶态RuO2颗粒分散在六方晶系Co(OH)2薄片的表面.循环伏安、恒流充放电测试表明,Co/Ru=8/1的复合材料在碱性电解液中具有优良的电容性能和较高的比容量.

Abstract: The electrochemical properties of Ru doped cobalt hydroxides synthesized via homogeneous chemical co-precipitation were investigated in 6 mol·L-1 KOH solution by galvanostatic charge-discharge process and cyclic voltammetry(CV).It is demonstrated that Ru doped cobalt hydroxides exhibited good capacitive characteristic and high specific capacitance.The sample with a Co/Ru molar ratio of 8 /1 shows the optimized electrochemical performance,including capacitive property and discharge capacity.The microstructure and morphology of the obtained Ru doped hydroxides were characterized by X-ray diffraction(XRD) and scanning electron microscope(SEM).The amorphous structure of ruthenium dioxide nanoparticles and single-crystal structure of Co(OH)2 platelets were confirmed.Based on a structure analysis and electrochemical measurement,the reversible faradic reaction within electroactive materials is dominant for the capacitive characteristic and high capacity.
