I would like to suggest you to increase the scan rate, it plays a vital role. Also try to increase the potential range and look into the literature for similar materials. Good luck.

Khalil Khadim Hussain

You need to change the experimental conditions such as, scan rate ( fast and slow), potential window, and type of electrolytes. meanwhile search related literature for example
