Potential window

The electrochemical window refers to the potential range of the oxidation and restore current of the solvent on the electrode surface.The main factors that affect the size of the electrochemical window are the surface properties of the electrode.When water is used as a solvent, most of the electrochemical windows of ordinary electrodes are around 1-1.3V, but the windows of diamond-like electrode electrode can reach 3V.Generally speaking, when the electrochemical reactions performed in the aqueous solution, when the hydrolysis reaction affects your electrode reaction, the potential you set is best to be less than the electrochemical window of the solvent.

There is no effect, depending on your electrode and electrolyte nature, there will be a little difference in peak potential in different windows
