Your CV curve is not complete. It’s only taken for charging cycle. So can we take half cycle CV and still calculate Tafel slopes and exchange current density? Or is a complete CV cycle necessarily needed?

Dear Aniq Ibnu Aljizan The number in origin is shown as 1.45643E-7, which means 1.45643*10^-7. You can convert it as 0.45643*10^-6 or 0.45643 µ

How to find ECSA and Cdl??
@ibrahimnazemqader9153
@ibrahimnazemqader9153 8 ай бұрын
To find ECSA and Cdl in Tafel test experimental results, you typically need to perform additional measurements such as cyclic voltammetry (CV) and then use appropriate formulas. The ECSA can be calculated using the formula: ECSA=Q/(C⋅A) Where: Q is the charge associated with the hydrogen adsorption/desorption reaction, C is the specific capacitance of the electrode material, A is the surface area of the electrode. Cdl can be calculated using the formula: Cdl=(dQ/dE)/(2⋅π⋅v) Where: dQ/dE is the slope of the capacitive current peak in CV curve (measured in ampere/volt), v is the scan rate (measured in V/s).

Redo experiment. Try to eliminate sources of error. Check for limiting current (peaks in your I vs V graph). You want to use a region that is kinetically current limited not mass transport limited. Attempt faster/slower scan rate CVs to perhaps obtain larger potential range.

Really, it was only for demonstration. I have deleted everything including Excel file. Sorry about that However, you can use my another video about digitizing any graph. You can find any related plot in literature and conver it to data. Also you can compare your results with that perticular reference.

@ibrahimnazemqader9153
@ibrahimnazemqader9153 3 жыл бұрын
@sara samreen basically, slope can be found by dividing y-axis to x-axis. In the straight line, you have to choose two points, then determine their corresponding x and y values. However, in this case, you don't need to find slope manually. Please use Origin software to find the slopes.
