Dataset of the work “Bidimensional Spectroelectrochemistry with Tunable Thin-Layer Thickness”

The parallel configuration provides information about chemical species present in the diffusion layer, meanwhile the normal arrangement supplies information about changes occurring both in the diffusion layer and, mainly, on the electrode surface.

The choice of a suitable cell to perform Bidim-SEC experiments is critical, especially while working under a thinlayer regime. So far, most of the proposed Bidim-SEC cells rely on the use of spacers to define the thin-layer thickness, which leads to working with constant thickness values. Herein, we propose a novel Bidim-SEC cell that enables easy-to-use micrometric control of the thin-layer thickness using a piezoelectric positioner.
