A Mechanistic Study on the Formation of Silver Nanoplates in the Presence of Silver Seeds and Citric Acid or Citrate Ions

Morphological evolution and reconstruction of silver nanoparticles in aquatic environments: The roles of natural organic matter and light irradiation

“…To obtain structural information about the silver nanoplates, we conducted HRTEM and EDS studies with silver nanoprisms, as shown in Fig. 4G and H. The fringe spacing was measured to be approximately 2.51 Å and 2.48 Å for SRHA and SRFA, respectively, which corresponds to the spacing between the (4 2 2) planes of fcc silver [34,35]. EDS further confirmed that the nanoprisms were composed of silver.…”

Synthesis of Large Bumpy Silver Nanostructures with Controlled Sizes and Shapes for Catalytic Applications

“…Because citrate ions act as a capping agent which preferentially binds to Ag (111) facets (the planar surface of nanoplates), they hinder the reduction of Ag + on the Ag (111) facets and induce crystal growth along Ag (100) facets (the side surface of nanoplates). 19,20 Therefore, at a lower Ag + concentration (5 mM), Ag + would less likely penetrate the citrate ion layer on the Ag (111), and is supposed to be less rapidly, and thus more evenly reduced on the Ag (111), simply increasing the 3(c)). Interestingly, when the Ag + concentration reached 500 mM, the nucleation occurred not only on the nanoplates but also in the reaction mixture, finally building up networked structures (Figure 3(d)).…”

“…Citrate ion is known to play an essential role in determining the structure of silver nanomaterials. [19][20][21] In our synthetic method, the presence of citrate ion is inevitable owing to their initial role to protect the nanoplate seeds. 4 To investigate the effect of the citrate ion on the final structure, we lowered the citrate concentration to 7.3 μM and observed plate-like flat and thick structures that were, however, branched on the side edges ( Figure 5(a), diameter = 226 ± 34 nm, thickness = 21 nm).…”

Synthesis and electrical properties of silver nanoplates for electronic applications

“…In recent years, a lot of research studies have been focused on the growth and properties of twodimensional silver (Ag) nanomaterials due to their amazing ability to control optical properties and their promising applications in optics, photonics, electronics and biotechnology [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. For example, silver nanostructures melting at a temperature well below the melting point of the bulk metal can be used as conductive fillers in electrically conductive adhesives (ECA) for application in microelectronic packaging [12,13].…”

“…Therefore, it is very essential to develop a simple and effective preparation method of silver nanoparticles with controlled size and * E-mail: wangzsedu@126.com shape [1][2][3][4][5][6][7][8][9][10][11][14][15][16][17][18][19][20][21][22]. The methods of synthesis of silver nanostructures mainly include solvothermal/hydrothermal processes [22,25] and, photoinduced [4], seed-mediated growth [3,20,21] as well as template [1,18] methods.…”
