Case Study

Effect of 4-phenyl-3-buten-2-one on Zinc Electroreduction

Perek-Dlugosz, Aleksandra, et al. Electrochimica Acta 123 (2014): 412-418.

To investigate the influence of 4-phenyl-3-buten-2-one (BDA) addition on the zinc reduction process, voltammetric measurements were carried out in S0 + 1 × 10⁻³ M ZnCl₂, S0 + 1 × 10⁻³ M BDA solutions, and their mixture (S0 + 1 × 10⁻³ M ZnCl₂ + 1 × 10⁻³ M BDA) at a scan rate of 0.1 V s⁻¹. The figure presents the cyclic voltammograms recorded in the BDA solution (S0 + 1 × 10⁻³ M BDA) and zinc-containing solutions with and without BDA (S0 + ZnCl₂ and S0 + 1 × 10⁻³ M ZnCl₂ + 1 × 10⁻³ M BDA).
From the figure (curve a), it can be observed that BDA undergoes reduction in two steps (-1.12 V and -1.32 V), with reduction potentials lower than that of zinc reduction. Adding BDA to the zinc solution results in significant changes in the voltammogram shape and current intensity (curve c). It is clearly evident that the peak potential corresponding to zinc reduction shifts to a more negative potential by approximately 0.24 V, reaching a value of -1.28 V.
A comparison of curves a and c in the figure reveals the presence of a peak at -1.12 V. Furthermore, a poorly defined and slightly visible peak is observed at -1.32 V in the voltammogram recorded for the ZnCl₂ and BDA mixture (curve c). This indicates that the first peak (C1) at -1.12 V (curve c) corresponds to the first step of BDA reduction and that Zn ions do not affect the reduction of BDA. Meanwhile, BDA inhibits zinc reduction at -1.04 V.
These results demonstrate that the presence and chemical properties of BDA influence the zinc deposition and stripping processes.
