Synthesis of Ag‐Ag₂S Heterodimers with Enhanced Violet Emission

Abstract

Ag-Ag 2 S heterodimers with good dispersibility were prepared in polyethylene glycol 400 (PEG400) at 160°C. The possible formation mechanism was proposed along the "CH 3 COOAg/Ag 2 S-Ag 2 O/Ag 2 S-Ag/Ag 2 S" route. The products [a] Figure 4. (A) The XRD patterns of the products from the mixture of PEG400, AgNO 3 and S powder: (a) 100°C, 10 min, (b) 100°C, 30 min, (c) 120°C, 10 min. (B) The possible growing mode of Ag-Ag 2 S heterodimers.4052 uid was obtained. The postprocessing of the products were the same as that of the Ag-Ag 2 S heterodimers. Preparation of Ag 2 S Nanomaterials4 mmol sulfur powder were weighed into a 100 mL round flask while some 40 mL PEG400 and 1 mmol AgNO 3 were added. The mixture was kept at 100°C for 10 min under mild magnetic stirring and then the black turbid liquid was obtained. The postprocessing of the products were the same as that of the Ag-Ag 2 S heterodimers. Conflicts of InterestThere are no conflicts to declare.

Interfacing Ag2S Nanoparticles and MoS2 Nanosheets on Polypyrrole Nanotubes with Enhanced Catalytic Performance

“…Similar to MoS 2 NSs, small Ag 2 S NPs are easy to agglomerate, which will considerably decrease their catalytic performance. , One of the most efficient strategies to solve these obstacles is to synthesize composite catalysts by merging Ag 2 S NPs with the supporting matrix. Some works have been reported to disperse Ag 2 S NPs on various nanostructured supporting materials, and this can effectively solve the Ag 2 S NP aggregation and improve their catalytic performance. − …”
