Development and Use of a Cyclic Voltammetry Simulator To Introduce Undergraduate Students to Electrochemical Simulations

Abstract

Cyclic voltammetry (CV) is a popular technique for the study of electrochemical mechanisms because the method can provide useful information on the redox couple. The technique involves the application of a potential ramp on an unstirred solution while the current is monitored, and then the ramp is reversed for a return sweep. CV is sometimes introduced in undergraduate chemistry laboratories. The CV waveform is dependent on several processes including charge transfer, diffusion, and coupled homogeneous reactions. Computer simulations are sometimes used to study these effects. An easy-to-use CV simulator was written in Microsoft Excel for the purpose of teaching undergraduate students and to serve as an entryway to more sophisticated electrochemical simulations.

Characterization and Electrochemical Analysis of Microelectrodes and the Interface with a Fabricated 3D-Printed Microfluidic Chip in an Upper-Division Analytical Course

“…Students observed three specific design patterns: a flat glassy carbon, a gold pillar, and a gold microarray. In introductory electrochemistry laboratory experiments, flat glassy carbon electrodes are frequently utilized. , Students visualized a flat, glassy carbon electrode that was modified with platinum (Pt) black (Figure A). The platinum black was included on the electrode as a catalyst .…”

Ajuste no lineal de técnicas electroquímicas

“…Otra ventaja de programar simulaciones electroquímicas en una hoja de cálculo, (J. H. Brown, 2015) es que el usuario puede modificar valores de las variables independientes del sistema en estudio y observar cómo dicho parámetro afecta a la señal de respuesta. Esta característica es muy útil en la práctica docente puesto que no siempre es fácil tener una serie de experimentos don de se aprecie la influencia de una variable, de modo que la simu-lación se presenta como una alternativa económica para entender sistemas electroquímicos en situaciones donde es complicado acceder a datos experimentales.…”
