AbstractThe localized electrodeposition of Ag on Au coated with self-assembled monolayers (SAMs) by scanning electrochem. microscopy (SECM) is reported. The SAMs were ω-functionalized alkanethiols X-(CH2)2SH, X = OH, NH2, CO2H, SO3H, as well as 4-mercaptobenzoic acid. The SAMs were characterized by XPS and cycling voltammetry (CV). The anodic dissoln. of a Ag microelectrode, which was held within a few microns from the Au surface, formed a well-controlled flux of Ag+. Deposition of Ag nanostructures was driven by the electrochem. redn. of the Ag+ on the Au surface. The effect of the functional group on the Ag local deposition was studied and compared with bulk deposition on the same SAMs. For bulk deposition, the interaction between Ag+ ions and the functional group of the alkanethiols slowed the kinetics of Ag deposition, shifting the deposition to potential that is more neg. and caused the formation of large, well-faceted Ag crystals. A clear correlation between the potential shift value and the morphol. of deposited Ag was obsd. The local deposition of Ag showed distinct difference compared to bulk deposition. A continuous and homogeneous Ag film was formed locally below the Ag microelectrode in the presence of a 3-mercaptopropionic acid monolayer. This was obsd. when a 120 s delay between the electrogeneration of the Ag ions and the application of a neg. potential to the Au surface was applied. Also, the potential applied to the Au surface also affected deposition. The deposited Ag was recollected by the Ag microelectrode by stripping the Ag from the Au surface while holding the microelectrode in the same position. This enabled calcg. the thickness of the Ag film deposited on the Au coated with 3-mercaptopropionic acid. Addnl. expts. clearly indicated that the mechanism of deposition involved complexation of Ag ions by the SAM and their local redn., which commenced prior to applying a neg. potential to the Au surface.

AbstractA flow-through electrode made of a C nanotubes (CNT) film deposited on a polytetrafluoroethylene (PTFE) membrane was assembled and employed for the detn. of low concn. of Cu as a model system by linear sweep anodic stripping voltammetry (LSASV). CNT films with areal mass ranging from 0.12 to 0.72 mg cm-2 were characterized by measurement of sheet resistance, H2O permeation flux and capacitance. Also, CNT with two different sizes and PTFE membrane with two different pore diams. (0.45 and 5.0 μm) were evaluated during the optimization of the electrode. Thick layers made of small CNT exhibited the lowest sheet resistance and the greatest anal. response, whereas thin layers of large CNT had the lowest capacitance and the highest permeation flux. Electrodes made of 0.12 mg cm-2 of large CNT deposited on 5.0 μm PTFE enabled sufficiently high mass transfer and collection efficiency for detecting 64 ppt of Cu(II) within 5 min of deposition and 4.0 mL min-1 flow rate. The anal. response was linear over 4 orders of magnitude (10-9 to 10-5 M) of Cu(II). The excellent performance of the flow-through CNT membrane integrated in a flow cell makes it an appealing approach not only for electroanal., but also for the electrochem. treatment of waters, such as the removal of low concns. of heavy metals and orgs.
