CASANOVA, R et al. CHARACTERIZATION OF IRON PHYLLOSILICATE CATALYSTS BY MEANS OF KLL AUGER SPECTRA OF OXYGEN. Rev. LatinAm. Met. Mat. [online]. 2002, vol.22, n.2, pp.78-81. ISSN 0255-6952.

In this work, we present a surface characterization of iron phyllosilicate catalysts synthesized with the ammonia method performed by using X-ray excited Auger spectra (XAES) together with XPS data. The detailed study of the O KLL region shows that the oxygen atoms, in this catalyst, are bonded differently to silicon or phyllosilicate (Si2O5) than in SiO2. This report shows that exist compounds that the mere consideration of the Auger parameter and their related is not sufficient for the complete identification, then it has been necessary the detailed study of the O KLL region Auger structure.
