Electrochemical methods, fundamentals and applications

Abstract: This book is intended to serve as both a course text at the senior-graduate level and as a reference book for those who wish to evaluate electrochemical methods as research tools. It should find wide use for both purposes. The content is narrower than the title may suggest. It is restricted to those aspects of electrochemistry in which the interplay of current flow and mass transfer at a microelectrode is of central importance.The first four chapters, which provide background for the rest of the text, assume t… Show more

“…The I k could be calculated from the Koutecky-Levich equation based on the ORR polarization curves. [28] The Pt 3 In/C-T700 catalyst exhibits an outstanding mass activity of 0.71 mA mg −1 Pt at 0.9 V (vs RHE), which is almost 2.2, 2.8, and 4.2 times larger than that of Pt 3 In/C-T550 (0.33 mA mg −1 Pt ), Pt 3 In/C-T400 (0.25 mA mg −1 Pt ), and commercial Pt/C catalyst (0.17 mA mg −1 Pt ), respectively (Figure 4c). The specific activity of Pt 3 In/C-T700 catalyst at 0.9 V is calculated to be 0.91 mA cm −2 Pt , which is close to Pt 3 In/C-T800 (0.8 mA cm −2 Pt ) but shows 2.8, 4.3, and 2.7 times higher than that of Pt 3 In/C-T550 (0.32 mA cm −2 Pt ), Pt 3 In/C-T400 (0.21 mA cm −2 Pt ), and commercial Pt/C catalyst (0.34 mA cm −2 Pt ), respectively.…”

“…Unlike common metabolites (e.g., glucose or lactate) whose detection relies on the specific enzymes, electroactive molecules can directly lose or donate electrons on the electrode surface when a redox potential is applied to the sensing electrode . LSV and CV, which involve linearly stepped potentials, are usually employed as the first strategy to evaluate the electrochemical behavior of electroactive molecules on a specific working electrode due to the simple and rapid operation .…”
