abstract = "In this study we report of considerable promotion of supercapacitive performances of ruthenium oxide hosted by perovskite-like structure of rare earth–CoO3 composite and vice versa. Spherical, sub-µm-sized, regular spheres of La0.6Sr0.4CoO3 (LSCO) were synthesized by ultrasonic spray pyrolysis (USP). The sphere surface was subsequently hydrothermally doped by RuO2. LSCO and LSCO/RuO2 composites were investigated for their supercapacitive performances in alkaline solution. Microstructure and surface morphology were studied by scanning electron microscopy (SEM) and X-ray diffraction (XRD). It was found that amorphous Ru species decorate the surface of LSCO spheres, and possibly incorporate partially into a B-site of the LSCO lattice. Electrochemical characterization by cyclic voltammetry (CV) clearly revealed that capacitive performances of LSCO are considerably improved by 20 mass% addition of RuO2. The registered capacitance for LSCO/RuO2 reaches the values of USP-synthesized pure RuO2, which reveals the promoting influence of LSCO on RuO2 pseudocapacitance. This intrinsic interactive promotion introduces the LSCO/RuO2 composite as a unique supercapacitive material.",
