This dataset contains the data presented in the figures of pulbished paper "One-dimensional polymer-derived ceramic nanowires with electrocatalytically active metallic silicide tips as cathode catalysts for Zn-air batteries" RSC Advances 11 39707 (https://doi.org/10.1039/D1RA05688C)
The electrochemical characterisation data, which was measured in University of Tartu Institute of Chemistry, is for Figures 5, 7, S5-S7 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. The working electrode was glassy carbon electrode with diameter of 5 mm.  

For Figures 5, 7, S7 electrochemical data the measured currents have been converted from current (A) to current densities (mA/cm2).
For Figure S5 and S6 electrochemical data the measured currents have been converted from current (A) to current densities (µA/cm2).
For Figures 5, 7, S7, the background currents, measured in Ar-saturated solution, have been subtracted, in addition to conversion to current densities.
