Iron ions in ZSM-5 zeolite: Fe³⁺ in framework, Fe²⁺ in extra-framework positions in catalytic N₂0 decomposition

Fe-ZSM-5 samples containing a combination of ⁵⁷Fe³⁺ in framework (FW) and regular iron in extra-framework (EFW) sites were prepared by introducing ⁵⁷Fe in hydrothermal synthesis, then exchanging Fe²⁺ of natural i...

X-ray powder diffraction study of chromium-vanadium oxide compounds prepared by “soft chemistry” methods

A novel aqueous method was used to synthesise mixed chromium-vanadium oxide hydrates with various chromium content, via the reaction of peroxo-polyacids of chromium and vanadium. The resulting materials are ge...
