Aloisi et al. [337] have performed in situ STM and electrochemical investigations of oxidative UPD of sulfur on Ag(lll). Electrodepositions of silver selenide [338], silver telluride thin films [339], and silver selenide nanowires [340] have also been described. 

The electrodeposition of silver from chloroaluminate ionic liquids has been studied by several authors [45-47], Katayama et al. [48] reported that the room-temperature ionic liquid l-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM]BF4) is applicable as an alternative electroplating bath for silver. The ionic liquid [EMIM]BF4 is superior to the chloroaluminate systems since the electrodeposition of silver can be performed without contamination of aluminum. Electrodeposition of silver in the ionic liquids 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF4) and l-butyl-3-methylimidazoliumhexafluorophosphate was also reported [49], Recently we showed that isolated silver nanoparticles can be deposited on the surface of the ionic liquid Tbutyl-3-methylimidazolium trifluoromethylsulfonate ([BMIMJTfO) by electrochemical reduction with free electrons from low-temperature plasma [50] (see Chapter 10). This unusual reaction represents a novel electrochemical process, leading to the reproducible growth of nanoscale materials. In our experience silver is quite easy to deposit in many air- and water-stable ionic liquids. 

Vandeputte et al. [122] used both of these equations to derive more accurate values of the constants than could be obtained from the Koutecky-Levich analysis alone, and hence derived rate constants for the predissociation of the thiosulfate complex involved in the electrodeposition of silver from thiosulfate solutions. 

The electrodeposition of silver, Ag, has been reported in a neutral EMIBF4 ionic liquid [80]. Silver tetrafluoroborate, AgBp4, dissolves in the ionic liquid up to about... 

The electrodeposition of silver, Ag, has been investigated in a EM1N(CF3S02)2 ionic liquid [101-103]. A monovalent silver species is introduced by dissolving AgN(CF3S02)2, which is prepared by the reaction of Ag20 with HN(CF3S02)2-The electrodeposition of metallic Ag is possible by the reduction of Ag(l). The formal potential of Ag(l)/Ag is estimated as around 0.5 V vs. Fc/Fc" " [103].

Controlled electrodeposition of silver and gold nanoparticles by the electrochemical double-pulse technique delivers samples with varying particle size from 10 to 500 nm and varying particle density. 

His research group successfully started extensive investigations on the electrodeposition of silver [24—26] and gold [26] nanoparticles on graphite surfaces. Combined with Brownian dynamic simulations for the growth of metal nanoparticle ensembles [22, 23], the work focused on the development of nontemplate, electrochemical routes to dimensionally uifiform metal structures. 

The electrodeposition of silver nanoparticles on 1.32 cm ITO substrates was performed in separate Teflon cells of 12 ml volume using a standard three electrode setup, as previously described for silver particles [29, 30]. The electrolyte used for the silver deposition contained 0.1 M KNO3, 0.1 M KCN, and 0.01 M AgNOs per liter. 

Recent investigations on the electrodeposition of silver demonstrated that the double-pulse method is a suitable technique for controlling the nanoparticle preparation, if the pulse parameters are carefully chosen and adjusted to the desired particle structure [29, 30]. Whereas particle density can be controlled via the overpotential and duration time ti of the nucleation pulse 1, the particle size can be enlarged by the growth time 2 (Fig. 8.5, [30]). 

Simple experimental conditions for an investigation of the relation (5.28) can be obtained in the case of electrodeposition of silver on silver single crystal faces prepared by the capillary technique [5.29, 5.74, 5.75]. As already shown, such crystal faces are usually intersected by only a few single screw dislocations which produce growth pyramids or cones with an uniform slope (cf. Fig. 5.31). The parabolic dependence (5.28) has been experimentally found in the systems standard AgQtkl)/...
