• Synthesis and characterization of RuO$_2$ thick film supercapacitor electrode: the effect of low temperature

This study involves the preparation of ruthenium oxide (RuO$_2$) thick films by a different method than those reported in the literature and the investigation of their dielectric properties. The substrates were coated with RuO$_2$ thick films deposited using a mixture of invertase enzyme and ruthenium ions dissolved in water. Scanning electron microscopy- energy dispersive X-ray spectroscopy was employed for surface analysis of the films. Current/potential measurementswere used to examine dielectric properties and X-ray diffraction to examine structural properties. The capacitance per unit mass of RuO$_2$ thick films produced with invertase enzyme in amorphous structure was found to be 845 F g$^{-1}$.Regarding energy dispersive X-ray spectroscopy analysis, thick films were found to contain around 79.15% ruthenium, evenly distributed on the surface of the films. In addition, we performed capacitance measurements for different temperatures and got very interesting results.
