Quantitative analysis of a mixture with reversible electrode processes by cyclic voltammetry and linear sweep voltammetry

PtRu /MWCNTs anodic catalyst was synthesized by hydrothermal treatment.The electrocatalytic oxidation of methanol was studied by cyclic voltammetry,linear sweep voltammetry,chronoamperometry and impendance spectroscopy.It was found that PtRu/MWCNTs catalysts synthesized in hydrothermal condition had higher electrocatalytic activities and better tolerance to poisoning species in methanol oxidation than that of PtRu/Vulcan XC-72.

Polymer/graphene quantum dots (PGQDs) composite electrochemical sensors are used for the detection of glucose. The PGQDs composite were synthesized by situ chemical oxidation polymerization method. The optical properties was studied by UV-Visible spectroscopy, the surface morphology by Field emission scanning electron microscopy (FESEM), the electrochemical performance and glucose detection were investigated by cyclic voltammetry (CV) and linear sweep voltammetry (LSV) reveals that PGQDs nanocomposite shows the enhanced electrocatalytic activity towards the oxidation and reduction and which enhances the electrochemically catalytically current during cyclic voltammetry. It exhibits the stable electrochemical sensors for detection glucose and good agreement with regression value R2=0.965.

Going Beyond Sweep Voltammetry: Alternative Approaches in Search of the Elusive Electrochemical Stability of Polymer Electrolytes

Solid polymer electrolytes (SPEs) are promising candidates for solid-state lithium-ion batteries. Potentially, they can be used with lithium metal anodes and high-voltage cathodes, provided that their electrochemical stability is sufficient. Thus far, the oxidative stability has largely been asserted based on results obtained with sweep voltammetry, which are often determined and reliant on arbitrary assessments that are highly dependent on the experimental conditions and do not take the interaction between the electrolyte and the electrode material into account. In this study, alternative techniques are introduced to address the pitfalls of sweep voltammetry for determining the oxidative stability of SPEs. Staircase voltammetry involves static conditions and eliminates the kinetic aspects of sweep voltammetry, and coupled with impedance spectroscopy provides information of changes in resistance and interphase layer formation. Synthetic charge–discharge profile voltammetry applies the real voltage profile of the active material of interest. The added effect of the electrode active material is investigated with a cut-off increase cell cycling method where the upper cut-off voltage during galvanostatic cycling is gradually increased. The feasibility of these techniques has been tested with both poly(ethylene oxide) and poly(trimethylene carbonate) combined with LiTFSI, thereby showing the applicability for several categories of SPEs.
