Synthesis and Characterization of (Ru-Sn)O2 Nanoparticles for Supercapacitors
ABSTRACT
The electrode materials SnO2, RuO2 and (Sn-Ru)O2 were synthesized through precipitation method from SnCl2·2H2O and RuCl2·2H2O solutions. The obtained nano-sized pristine products were characterized using X-ray diffractometry, Scanning Electron Microscopy (SEM), differential scanning calorimetry (DSC)-thermogravimetric analysis (TGA) and cyclic voltammetry (CV). The Debye–Scherrer formula was used to estimate the average size of the nanoparticles SnO2 (36 nm), RuO2(24 nm), and (Sn-Ru)O2 (19 nm). Electrochemical studies were carried out to examine the capacitance of SnO2, RuO2, (Sn-Ru)O2 electrodes in 0.5 M H2SO4 at various scan rates. The estimated electrode capacitance was de-termined to decrease with an increase of scan rate.
