Their specific surface area was determined with the BET technique (adsorption of nitrogen, with degassing system Micromeritics, Norcross, GA, USA). Their surface oxidation was determined with XPS (X-ray Photo Spectroscopy, Quantera Scanning XPS microprobe, Physical Electronics, Chanhassen, MN, USA)....
The specific surface area and porosity were estimated through the Brunauer–Emmet–Teller (BET) method using the 3 Flex instrument (Micromeritics). BET is a surface characterization technique based on the physical absorption of gas molecules on a solid surface in a monolayer form under the effect ...

In the conclusion of his article, Lecloux proposes that the ''BET-specific surface area should not be used to calculate the VSSA value because it takes into account the internal porosity of the particles''. Instead, he proposes the use of a method he described in ...

Specific surface area was measured on 1.6mm and 0.7mm and 0.07mm particle sizes. Specific surface area was measured with the standard BET method while porosity was measured with mercury porosimetry after conformance and blank correction. Additional porosity measurements were performed using the crushed ...
