Enhanced Supercapacitance of Hydrous Ruthenium Oxide/Mesocarbon Microbeads Composites toward Electrochemical Capacitors

A facile hydrothermal strategy was proposed to synthesize RuO⋅HO/mesocarbon microbeads (MCMBs) composites. Further physical characterizations revealed that RuO⋅HO nanoparticles (NPs) were well dispersed upon the surfaces of the MCMB pretreated in 6 M KOH solution. Electrochemical data indicated that...

description: A facile hydrothermal strategy was proposed to synthesize RuO⋅HO/mesocarbon microbeads (MCMBs) composites. Further physical characterizations revealed that RuO⋅HO nanoparticles (NPs) were well dispersed upon the surfaces of the MCMB pretreated in 6 M KOH solution. Electrochemical data indicated that the RuO⋅HO/MCMB composites owned higher electrochemical utilization of RuO species, better power property, and better electrochemical stability, compared with the single RuO phase. The good dispersion of RuO⋅HO NPs and enhanced electronic conductivity made the H ions and electrons easily contact the RuO⋅HO phase for efficient energy storage at high rates.
