Rapid synthesis of silver nanostructures by using microwave-polyol method with the assistance of Pt seeds and polyvinylpyrrolidone

Morphology Control of Silver Related Materials by Ultrasonic Irradiation

“…Thus, it is conjectured that needle-shaped Ag 2 CO 3 are grown from the nanorods that act as seeds during freeze-drying. 15 As previously mentioned, Ag 2 CO 3 was produced at 22.9 kHz for high silver ion concentrations. However, in the case of bubbling argon gas in distilled water, the formation of Ag 2 CO 3 reduced in 22.9 kHz.…”

Syntheses of Silver Nanowires in Liquid Phase

“…All previous reports of the synthesis of silver nanowires from an AgNO 3 /Cl -/PVP/EG solution described that it is necessary to remove the oxygen dissolved in the reaction solution in order to achieve the growth of silver nanowires. Recently, our group [20][21][22][23] and Gou et al [24] found that the mechanism described above is not applicable to the synthesis of Ag nanowires under rapid microwave(MW)-polyol method in the presence of Cl -anions because one dimensional (1D) structures were produced preferentially from unstable decahedrons even in the presence of O 2 . It was predicted that not only Cl -from NaCl, but also O 2 dissolved in EG probably takes part in the shape-selective evolution of Ag 1D products.…”

Interactive effect of agitation rate and oxidative etching on growth mechanisms of silver nanowires during polyol process

“…Moreover, the oxygen scavenging role of Cu CC/C redox pairs allows the MTPs to grow. [11,14,19,20] Another important point regarding introducing CuCl2 in polyol synthesis process of silver is the role of Cl ¡ ions. The presence of Cl ¡ reduces the concentration of free Ag C ions in the solution via the formation of AgCl which improves the electrostatic stability of the initially formed Ag seeds.…”

“…[18] Furthermore, the growth mechanisms of Ag nanostructures via microwave-polyol method in the presence of Pt as the catalyst have been studied. [19,20] They showed that PVP tends to be absorbed on the {111} facets at short heating time. Visaveliya and Kohler [21] realised the key role of ascorbic acid for tuning the aspect ratio during synthesis process of silver microrods.…”

“…[26] Moreover, gold nanocrystals with desired shape and size have been produced by applying proper oxidative etching of AuCl 4 ¡ and Cl ¡ anions. [19,20] Another important factor for controlling the kinetics of a synthesis process is stirring of the reaction system. The crystal morphology of CaCO 3 is simply controlled by variation of stirring conditions.…”
