Abstract

Transition metal oxide thin films are in great demand for a variety of technical applications, Ruthenium oxide is one of them having distinct structural, optical, chemical, and electrical properties. The structural and morphological characterization of Ruthenium oxide thin film electrodes created using the sol-gel spin coating process is covered in this work. For annealing, temperatures between 200°C and 900°C were employed. To examine electrochemistry, cyclic voltage measurement and chronopotentiometry were used. It showed the maximum specific capacitance of 464 F/g in 0.1 M KOH electrolyte, Specific Power of 36 kW/kg, and Specific Energy of 3.96 Wh/kg for Ruthenium oxide electrode annealed at 900°C. This study describes the structural and morphological changes that occur as annealing temperature increases.
