This dataset contains the data presented in the figures of pulbished paper "Outstanding platinum group metal-free bifunctional catalysts for rechargeable zinc-air batteries" Electrochimica Acta 446 142126 (https://doi.org/10.1016/j.electacta.2023.142126)
The electrochemical characterisation data, which was measured in University of Tartu Institute of Chemistry, is for Figures 2, 3, 4, 5, 6  and the nomenclature of the catalysts is the same as in the mentioned article.

Data was collected using Autolab potentiostat/galvanostat PGSTAT30 (Metrohm Autolab, The Netherlands) controlled with NOVA version 2.1.4 software.
An in-house built device was used to study the catalysts performance and stability in Zn-air battery conditions.

For Figures 2, 3, 4, 5a electrochemical data, the applied currents have been converted from current (A) to current densities (mA/cm2).
For Figures 2, 3, 4, the background currents, measured in Ar-saturated solution, have been subtracted, in addition to conversion to current densities.
For Figures 5b, 6 electrochemial data, the time (s) has been converted to time (h).
