      vs. Ag wire was used for simultaneous co-deposition of metals and exfoliation of graphite. The reduction potential of these metals are typically much lower than the intercalation potential of Li+ or TEA+. For example, the electrodeposition of Au on graphite surface was observed at −0.4 V . vs…

      Nucleation phase consisting of two separated periods with cathodic pulses (totally 5 seconds) followed by a shorter period with anodic polarization. Growth phase with cathodic and anodic pulses for 0.5 and 0.1 second respectively. The current densities were typically 47 mA/cm2 and 60 mA/cm2 for the cathodic and anodic pulses, respectively.

      For cathodic electrosynthesis, carbon-based electrodes perform well because of their poor efficiency for the 4e− ORR. The efficiency with which these catalysts produce H 2 O 2 can be further improved by adding dopants or metal nanoparticles. For the anodic route, metal oxides such as CaSnO 3, BiVO 4 and WO 3 perform well. Many of these ...

      Anodic stripping voltammetric behavior of the films is to be evaluated in terms of trace heavy metals, such as Zn, Pb, Cu, Hg, etc., by using linear sweep anodic stripping voltammetry. The relationship between the microstructure and electrochemical properties of the films will be systematically investigated.

      The values of corrosion current densities and corrosion potentials are often determined by Tafel analysis (extrapolation of linear segments of anodic and cathodic branches of polarisation curves towards their intersection in the semi-logarithmic, E vs log I, plane).

      The zinc casing serves as the anode and is consumed in the anodic electrode reaction Zn(s) --> Zn2+ + 2e-; the zinc ion dissolves in the moist ZnCl2-NH4Cl electrolyte. A carbon rod serves as the cathode, but it is chemically inert. The cathodic electrode reaction which consumes MnO2 is best written as:

      Hence, Anodic Stripping Voltammetry (ASV) and Cathodic Stripping Voltammetry (CSV) are two specific stripping techniques. The attached paper by Bott discusses stripping voltammetry in detail. In addition to varying the direction of the scan, the manner in which the potential is scanned may also differ.
