Fig. 16. Chemical maps of phosphate-activated zeolite clusters, constructed from Al and P K-edge spectra stacks for two different samples. Blue color denotes Al, red denotes P, resolution is 60 × 60 nm. (a-ii) and (b-ii) Al K-edge XANES spectra; (a-iii) and (b-iii) P K-Edge XANES spectra, spectra in (ii) and (iii) colored according to the color in the inset.
