Sažetak
Supercapacitive RuO2/reduced graphene oxide composites were synthesized by hydrothermal microwave-assisted single-step method at different temperatures. Syntheses were accomplished by simultaneous oxidation of Ru from RuCl3 and reduction of graphene oxide in solution of various pH. Capacitive responses of obtained samples were analyzed using combined electrochemical and quartz crystal nanobalance techniques. The cyclic voltammetry and electrochemical impedance spectroscopy have been performed in H2SO4 and Na2SO4 solutions. The analysis of obtained results showed that synthesized composites are of acceptable capacitive properties. The capacitive properties of composite synthesized at neutral pH showed weakly depandance on synthesis temperature, with moderate increase of the capaticance with increasing temperature. On the other hand, composite synthesized in alkaline conditions had the higest capacitive properties at average temperature in the examined range of temperatures.
