I am going to study the ORR , by CuO modified GC electrodes. Different papers give different potential range for studies.pl. clarify
For ORR, you could adjust your potential between 0 and 1.1 V vs. RHE. It depends also on the behavior of your electrode. some catalysts need more negative to be completely reduced like Ag. For RDE also you should notice the diffusion region.
You should try for your specific experimental conditions. The potential window cited by Hatem could be a good starting point,,,
As Juan suggests it depends on your experimental conditions, solvent, oxygen on your solvent, modification of your electrode, ect.
I think the best way is just to start with a small window using the solvent you will use in your later experiments. Then you broaden the window until you find the limits for your conditions.
