"The Redox Chemistry of Ruthenium Dioxide: A Cyclic Voltammetry Study—Review and Revision"
Abstract:
By cyclic voltammetry at high scan rates, the electrochemical properties of RuO2 in acidic and alkaline solutions were investigated in detail. Thirteen current peaks can be distinguished in sulfuric acid and sodium hydroxide. With respect to the pH sensitivity of RuO2 electrodes, we considered charge calculations, peak currents, and apparent diffusion coefficients. The nature of the Ru(II) oxidation was clarified by Ru(I)−Ru(III) species.
Hassan Nasser Abdelkader BOUAZIZ Natalia V. Zolotareva our results are. can you please guide me on this actually in these results I am a little bit confused about the results? Please share your knowledge on this
Dear Muhammad Danish Ali , looking at your curve it seems you are only measuring capacitive current, which is directly proportional to the scan rate...
What is your electrode ? I would say it needs to be better cleaned...
the positive peak relates to the oxidation, whereas the negative peak is associated with the reduction process of the electrolyte. the area inside the Red/Ox curve is related to the charge storage capacity. At higher scan rates the current density is usually high, however, if the shape of the peak (inner area) is decreased, the red/ox reaction is limited due to complex diffusion kinetics. The working potential window of each material is also a characteristic property of the material. In summary, the integrated area of the curve, the potential difference between the Reduction and oxidation peak, and current desity of the peaks are accountable measures of the CV peak. Scan rate sensitivity tells about the porosity and stability of the material.

Hello @all, my question is, I have a track irregularities Data and I have plotted the graphs but am lost on how to do the analysis and I was asked to analyze the Data using Time series analysis.
Hassan Nasser , Mumtaz Ali , Nicolas Murer , Abdelkader BOUAZIZ , and Natalia V. Zolotareva Thanks a lot for your guidance and suggestions. My manuscript is accepted.
