Structural features of AgCaCdMg2(PO4)3 and AgCd2Mg2(PO4)3, two new compounds with the alluaudite-type structure, and their catalytic activity in butan-2-ol conversion

Synthesis, crystal structure determination of a novel phosphate Ag1.64Zn1.64Fe1.36(PO4)3 with an alluaudite-like structure

“…Indeed, the existence of transition metals in the structure is often the origin of interesting properties viz. magnetic (Hatert et al, 2004), heterogeneous catalysis [e.g., the role of AgCaCdMg 2 (PO 4 ) 3 and AgCd 2 Mg 2 (PO 4 ) 3 in the conversion of butan-2-ol] (Kacimi et al, 2005), electronic conductivity and significant ionic mobility (Richardson, 2003).…”

Structure cristalline de type alluaudite KNa5Mn3(MoO4)6

“…Lors de l'exploration des systè mes A-Mn-Mo-O (A = ion monovalent), une nouvelle phase de formulation KNa 5 Mn 3 Mo 6 O 24 a é té synthé tisé e par ré action à l'é tat solide (tempé rature proche de 950 K). Un examen bibliographique montre que notre maté riau est de type alluaudite (Kacimi et al, 2005;Hatert, 2006).…”

Crystal structure of a sodium, zinc and iron(III)-based non-stoichiometric phosphate with an alluaudite-like structure: Na1.67Zn1.67Fe1.33(PO4)3

“…Alkali transition-metal phosphates belonging to the alluaudite family constitute one of the most diverse and rich classes of minerals, and have been studied intensively over the last few years. Owing to their outstanding physico-chemical properties, these compounds have many potential applications in various fields, such as catalytic activity (Kacimi et al, 2005) and as promising cathodes for sodium-ion batteries through the presence of mobile cations located in the tunnels of the open three-dimensional framework (Huang et al, 2015). In their recent study, Huang et al (2015) point out that the electrochemical performance is not only associated with morphology, but also with the electronic and crystalline structure.…”
