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…
Abstract Ruthenium oxide (RuO2) thin films have been prepared using single step chemical method containing Ru(III) Cl3 solution in an aqueous medium at low temperature. The structural, morphological and optical properties have been investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and optical absorption technique. The XRD stu…
a b s t r a c t Supercapacitors have been known for over fifty years and are considered as one of the potential energy storage systems. Research into supercapacitors is presently based primarily on their mode of energy storage, namely: (i) the redox electrochemical capacitors and (ii) the electrochemical double layer capacitor. The commonly investigated classes of materials are transition m…
