“…Nevertheless, they found use e. g. in cosmic applications and in warfare. AgO is antibacterial agent [123] and it finds limited use in organic chemistry, usually as a component of in situ prepared composites, and typically in oxidation reactions. [124,125] Ag 3 O 4 is a mixed valence Ag(II)/Ag(III) oxide.…”

The mini‐review is focused on application of silver and its compounds in fluoroorganic synthesis, and it reflects immense progress in this field which took place during the last two decades, with additional examples of reactivity of historical importance. Reactions of C−H, C−F, N−H and O−H bond functionalization, as well as catalysis of cycloaddition reactions and intramolecular rearrangement, retro‐rearrangement, and functional group migrations, have been described. Whenever available in original works, the reaction mechanisms were discussed. Since silver may be catalytically active in each of its available oxidation states from (0), via (I) and (II) to (III) with their immensely diverse properties, the organofluorine part is preceded by a brief overview of chemistry of silver in general. Uniqueness of silver among Group 11 elements is highlighted.

“…In recent years, the preparation of silver nanoparticles (Ag NPs) has advanced rapidly. Ag NPs possess unique electrical, optical, and catalytic properties, making them suitable for applications such as catalysts, new electrode materials for batteries, electrically conductive materials, and low-temperature thermally conductive materials [ 17 , 18 , 19 , 20 ]. Ag NPs can be prepared through physical or chemical methods.…”

This study focuses on the fabrication of fiber membranes containing different concentrations of AgNO3 via the electrospinning technique. The AgNO3 present in the fibers is subsequently reduced to silver nanoparticles (Ag NPs) through UV irradiation. The resulting nanofiber film is characterized using scanning electron microscopy, X-ray diffraction, and evaluations of its anti-UV and anti-electromagnetic radiation properties. Experimental results demonstrate that increasing the AgNO3 content initially decreases and then increases the fiber diameter and fiber diameter deviation. Under UV light, the nanofibers fuse and bond, leading to an increase in the fiber diameter. AgNO3 is effectively reduced to Ag NPs after UV irradiation for more than 60 min, as confirmed by the characteristic diffraction peaks of Ag NPs in the XRD spectrum of the irradiated AgNO3/PVB fibers. The nanofiber film containing AgNO3 exhibits superior anti-UV performance compared to the film containing AgNO3-derived Ag NPs. The anti-electromagnetic radiation performances of the nanofiber films containing AgNO3 and AgNO3-derived Ag NPs are similar, but the nanofiber film containing AgNO3-derived Ag NPs exhibits higher performance at approximately 2.5 GHZ frequency. Additionally, at an AgNO3 concentration of less than 0.5 wt%, the anti-electromagnetic radiation performance is poor, and the shielding effect of the nanofiber film on medium- and low-frequency electromagnetic waves surpasses that on high-frequency waves. This study provides guidance for the preparation of polyvinyl butyral nanofibers, Ag NPs, and functional materials with anti-ultraviolet and anti-electromagnetic radiation properties.
