This dataset contains the data presented in the figures of the published paper "Bifunctional Oxygen Electrocatalysis on Mixed Metal Phthalocyanine-Modified Carbon Nanotubes Prepared via Pyrolysis" ACS Appl. Mater. Interfaces 2021, 13, 35, 41507–41516 (https://doi.org/10.1021/acsami.1c06737)
The data is for Figure 4, Figure 5, Figure 6, Figure S5, Figure S6, Figure S8 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 all supplied electrochemical data the measured currents have been converted from current (A) to current densities (symbol, j) (mA/cm2, that is multiplied by 1000 and divided by electrode area=0.2 cm2).
For Figure 4a, Figure 5a, Figure S6a,S6c,S6e and Figure S8a, the background currents (measured in Ar-saturated solution) have been subtracted, in addition to conversion to current densities.
