The effect of support type and alloying with Sn on the electronic structure of supported Pt nanoparticles was investigated using in situ high energy resolution fluorescence-detected X-ray absorption near-edge spectroscopy (HERFD XANES) at the Pt L 3 -edge. Pt and PtSn particles supported on K-L zeolite have similar electronic structures in the presence of individual adsorbates (H 2 ...
Resonant inelastic X-ray scattering (RIXS) was applied to investigate whether the iron–oxygen species created upon reaction of Fe-ZSM-5 with N 2 O have a (partial) 3d 4 configuration, i.e. oxidation state Fe(IV). Fe-ZSM-5 samples with low iron loading were pre-treated at high temperatures before reaction with N 2 O. Then Fe K-edge XANES spectra were recorded either by selecting...
