Electrodeposited ruthenium oxide thin films for supercapacitor: Effect of sur…

A B S T R A C T Amorphous and porous ruthenium oxide thin films have been deposited from aqueous Ru(III)Cl3 solution on stainless steel substrates using electrodepositionmethod. Cyclic voltammetry study of a film showed a maximum specific capacitance of 650 F g-1 in 0.5 M H2SO4 electrolyte. The surface treatments such as air annealing, anodization and ultrasonic weltering affected surface m…
