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．
英文摘要：
The electrochemical properties of Ru doped cobalt hydroxides synthesized via homogeneous chemical co-precipitation were investigated in 6 tool·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.
