If you take an inorganic material like a mixed oxide cerium-zirconium.

(1) May we say that there is a natural limit in the SSA (m2/g), e.g. 200 m2/g?

My understanding is that there is a relationship between porosity and SSA. May we state that due to the limitation of the porosity, there is a limitation of the SSA?

(2) if the SSA is measured by the BET method, what is the limit of the method in terms of SSA?

Thank you !!
