Redox properties of (1-(2-pyridylazo)-2-naphthol)copper(II) encapsulated in Y Zeolite

Mono and bimetallic NaY catalysts with high performance in nitrate reduction in water

“…These peaks were attributed to the Cu 2+ /Cu + and Cu + /Cu redox couples, which constitute two steps of Cu 2+ /Cu reduction. The occurrence of a twostep process in this case is due to the stability of Cu + by the interactions between this metal ion and the zeolite framework [27]. However, the voltammogram of Pd-Y/CT shows oxidation and reduction peaks at 0.53 and À0.05 V vs. SCE attributed to the Pd 2+ /Pd redox couple (Fig.…”

Encapsulation of manganese(III) complex in NaY nanoporosity for heterogeneous catalysis

“…[6,34] The SEM results also confirm that Soxhlet extraction is a suitable method for removing the species adsorbed on the external surface of zeolite. It is clear from the micrographs that during complex encapsulation the crystallite of support remains unchanged and there is no indication of the presence of any metal ions, ligand or complex on the surface.…”

Copper(II)–imida‐salen Complexes Encapsulated into NaY Zeolite for Oxidations Reactions

“…Figure 1 (A) represents a morphology typical of the faujasite zeolite. Analysis of the micrographs of NaY and the heterogeneous catalysts shows that there are no changes in the zeolite morphology or structure upon encapsulation of the complex 13,18. It appears from Figure 1 that Soxhlet extraction was efficient and the surface is completely washed out, which indicates the complete removal of uncoordinated ligands and the remaining metal complexes are physically adsorbed on to the external surface of the zeolite 19.…”
