I used the hydrothermal method to create nanoparticles and adjusted the time and reaction temperature to produce catalysts of different sizes. To validate the change in surface area, I conducted a BET analysis and found a significant change in surface area and pore volume. It would be beneficial if I could also demonstrate the variation in electrochemical studies. I performed fundamental tests such as CV, LSV, and EIS. However, to measure the specific area, I aim to determine the electrochemically active surface area.
Please help me with this...
