In this work, AuCu nanocluster protected by triphenylphosphine and adamantane mercaptan is synthesized and it is formulated to [Au25Cu8(S-Adam)19(PPh3)5]+. With the characterization of UV-Vis absorption spectrum and Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF), the synthesis of [Au25Cu8(S-Adam)19(PPh3)5]+ nanocluster is demonstrated to be a size-focusing process: polydisperse AumCun(S-Adam)x(PPh3)y precursor with a size ranging from 900 Da to 2000 Da generates firstly and it transforms into [Au25Cu8(S-Adam)19(PPh3)5]+ nanocluster in 3 days. TEM image demonstrates it is monodisperse distributing between 0.84 and 2.0 nm with an average size of 1.4 nm. TG shows a weight loss of 38.70% with ligands continuously breaking down between 200 and 330°C. Thermal stability test shows that it keeps well thermal stability at 40°C: the peaks of UV-Vis absorption spectrum gradually get weaken at 6 h and completely become a decaying curve at 8 h. This work provides a simple method to prepare AuCu nanocluster and affords new ideas for preparing Au-based alloy nanoclusters.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"144 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140325493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How the phase composition changes at each site of the sample and how the phase compositions change for various types of phase reactions are considered. It is shown that the eutectic reaction can change to a peritectic reaction as temperature lowers during directional crystallization. A 29.96 Fe + 21.55 Cu + 2.01 Ni + 46.49 S (at %) melt was directionally crystallized. Since nickel is present in the ingot in the form of impurities dissolved in the phases of the Cu–Fe–S system, the behavior of the melt belonging to this three-component system could be involved in data interpretation. As a result, a sample has been obtained with three zones changing one another: single-phase FezS1 ± δ (Poss), a Poss + (Cu,Fe)1 + xS (Iss) two-phase eutectic mixture, and then single-phase Iss. The average composition of the solid phase changes from one discrete value to another in going to the next zone, while the melt and solid solutions in the neighboring zones have their compositions changing continuously. These results are consistent with theoretical ideas.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"48 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140100088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
