This dataset contains the data presented in the figures of published paper "Enhanced oxygen reduction reaction activity and durability of Pt nanoparticles deposited on graphene-coated alumina nanofibres", Nanoscale Advances 3(8) (2021) 2261-2268. DOI: 10.1039/D1NA00007A


This dataset contains data for Figures 4-7. 

The data was collected using Autolab potentiostat/galvanostat PGSTAT30 controlled with General Purpose Electrochemical System (GPES version 4.9.007) software. The measured currents (in A) have been converted to current densities (mA/cm2, that is multiplied by 1000 and divided by 0.126 cm2). For RDE curves, the background currents, measured in Ar-saturated solution, have been subtracted.
Catalyst nomenclature is as in the paper.
