Formation of Bi₂Ir nanoparticles in a microwave-assisted polyol process revealing the suboxide Bi₄Ir₂O

Abstract

The new suboxide Bi4Ir2O was found as an intermediate in the formation of the intermetallic phase Bi2Ir by a microwave-assisted polyol process.

“…CO 2 is also evolved by the amide formation of betaine and urea (Scheme 1b). In this process, bismuth(III) is not assumed to go into solution since no BiOCl formation is observed, which is expected for bismuth(III) ions dissolved in the presence of chloride [55] . This is in contrast to the reaction in [Hbet] 2 [NTf 2 ]Cl, where BiOCl precipitates.…”

“…Anschließend reagiert es zu Bi 2 Ir-Nanokristalliten. 39) Tambornino, Hoch und Mitarbeitende haben über das Cäsiumoxidmercurid Cs 18 (Hg 8 )O 6 berichtet, in dem erstmals ein nacktes, würfelförmiges (Hg 8 ) 6--Ion vorliegt (Abbildung 5). 40) Wie Kraus, Kartunnen und Mitarbeitende erneut bewiesen haben, ist es nicht nur möglich, neue Interhalogenverbindungen zu synthetisieren, diese lassen sich auch in anionischer Form im Festkörper stabilisieren: Sie synthetisierten die ersten Alkalimetall-Hexafluoridobromate(V), A[BrF 6 ] (A K, Rb), die im K[AsF 6 ]-Strukturtyp kristallisieren.…”

α-Ag2S nanoparticles: low-temperature syntheses, crystallisation pathway, and first operando luminescence measurements for sodium-ion battery applications

“…Thus, the polyol molecules chelate the solid nuclei during their formation, preventing agglomeration and assisting in the stabilisation of the NPs in the solvent. 21,22 The preparation of Ag 2 S NPs can be further optimised by exploring the use of single source precursors (SSPs). 23,24 SSPs are molecular structures that contain all the elements required to form inorganic products.…”
