Templated synthesis of silver nanowires based on the layer-by-layer assembly of silver with dithiodipropionic acid molecules as spacers

Convenient synthesis of silver nanowires with adjustable diameters via a solvothermal method

“…The most widely used methods for generating silver nanowires are various chemical routes, such as the polyol process [15,16], wet chemical synthesis [17,18], the hydrothermal method [19,20], ultraviolet irradiation photoreduction techniques [21,22], electrochemical techniques [23,24], DNA templates [25,26], and porous materials templates [27,28]. Among these methods, the polyol process is an effective route to synthesize silver nanowires.…”

Synthesis and characterization of the highest connected 3D Wells-Dawson POM/TMC hybrid

“…The Ag1 atoms complete its wry ''see-saw" geometry by two N atoms of two phnz molecules and two O atoms of P 2 W 18 cluster and O1W, respectively; The bond distances and angles around the Ag1 are 2.28(3) Å for Ag1-N1, 2.318(17)/2.429(16) for Ag1-O35/O1w, 107.03°for N1-Ag1-N1, 109.8(7)/118.65 (8)°for N-Ag-O/Ow, and 91.5(4) for O-Ag-O; Ag3 atoms are defined by two N atoms of two phnz molecules and two O atoms of different P 2 W 18 clusters, and its geometry looks as if a ''butterfly" preparing to fly, which decreases the steric hindrance and is favor of the formation of the high connectivity of the POMs. The bond distances around the Ag3 are similar to Ag1, namely, 2.24(2), 2.575(2), 2.268 (14) and 2.345(17) Å for Ag3-N3, Ag3-N2, Ag3-O1and Ag3-O34. But the bond angles are incomparable to those in Ag1, 86.83 (10) [11]) implies a weak binding, which results in slight difference from those in the tri-coordinated Ag complexes [12].…”

“…4. The peak potentials E 1/2 = (Epc + Epa)/2 are À561, À345 and À109 mV (30 mV s À1 ), respectively, corresponding to three consecutive two-electron processes of W. And the fourth irreversible anodic peak (IV) is assigned to the oxidation of Ag (I) at 118 mV [14]. The peak potentials change gradually following the scan rate from 30 to 300 mV s À1 : the cathodic peak potentials shift to the negative direction and the corresponding anodic peak potentials to the positive direction, and besides, the peak-to-peak separations between the corresponding anodic and cathodic peaks increased, but the average peak potentials do not change on the whole.…”

Keggin-Type Polyoxometalate Cluster Functionalized with Dinuclear M-H2biim (M = Cu, Ag) Metal–Organic Segments

“…Two redox couples, II-II 0 and III-III 0 in the CV, are observed for compounds 1-3, with mid-point potentials, E m , of -433.7 and -609.5 mV found for 1, -394 and -559 mV found for 2, -399.5 and -567 mV found for 3, are ascribed to the electrochemistry of the POM anions [31][32][33]. The reversible couple I-I 0 for compound 2, with mid-point potentials, E m , of -28.5 mV, and irreversible anodic peak I at about 230 mV for 1 and 300 mV for 3 are assigned to the oxidation of the Cu/Ag metal centers [34,35].…”
