I made TiO2/ACNF. It are TiO2 nanoparticles with an average size of 10nm on an Activated carbon nanofiber (ACNF). Also, TiO2 are embedded in the ACNF.

I conducted BET, CV and Aicd Titration analyses, but the results include contributions from the carbon fiber surface.

In addition, i attempted Positive ion(Na+, Li+) electroadsorption, but unfortunately, I did not achieve the desired results.

I need to only TiO2 nanoparticles surface area from TiO2/ANCF.

How can i get Active surface area of TiO2?

Please help me!
