Thanks Alan, How about Bronsted and Lewis sites using XRD?

Alexander B. Missyul’

XRD is a technique for the bulk analysis, while acidity is determined by the surface. You will need the surface-specific techniques.

N. S. Saxena

It is a good question, but I do not think that XRD can give you the acidity of gamma-alumina. I agree to the answers of Alan and A.B. Missyul .
