Need to know about the details of the TEM characterisation of activated carbon. What are all the information can be obtained from that? Is it possible to see and measure the pore size of the activated carbon?
TEM will only provide you a limited field of view into the carbon's structure. You cannot accurately measure pore size from TEM because pore size is characterized by an average of pore size ranges throughout the entire particle, and TEM will only show one portion of the particle. Additionally, TEM will only show the surface, and not the vast internal surface area of the activated carbon.
One use of TEM for studying activated carbon could be to measure the size of nanoparticles which have been added to modify the carbon surface. But SEM would probably work better in most cases.
