Cyclic voltammetry at the tubular electrode

Linear sweep voltammetry at the tubular electrode: Theory of EC mechanisms

“…A number of analytical theories have been developed for the tubular electrode in the Lévêque limit, where the diffusion layer is thin in comparison with the radius of the tube, a condition achieved for the highest flow rates [18][19][20][21]. In this Lévêque regime the analytical work encompasses not only a simple electron transfer, but also explores some preceding or subsequent homogeneous reaction and uses voltammetry rather than chronoamperometry.…”

Linear sweep voltammetry at the tubular electrode: Theory of EC2 mechanisms

“…A number of analytical theories have been developed for electron transfer reactions at a tubular electrode, including processes with a preceding or subsequent homogeneous step [16][17][18][19], and processes for which the heterogeneous step is irreversible or quasi-reversible [20]. These analytical theories apply only in the Lévêque limit where the flow profile at the electrode may be considered linear, a condition achieved at fast flow rates for which the diffusion layer is thin compared to the radius of the tube.…”

Theory of cyclic voltammetry in tubular electrodes under no flow conditions

“…Much work has been reported using the tubular hydrodynamic electrode, where the increased mass transport means that accurate, enhanced current responses may be obtained, and can be accurately described by the Levich equation [6,7]. Previous work on flow in tubes is varied, including analyses under Lévêque [7] conditions [8][9][10][11][12][13][14][15][16][17], the effect of various homogeneous mechanisms [18][19][20][21][22], voltammetry experiments and ESR responses or other sensing of species in tubular cells [23][24][25][26][27].…”
