Dataset title: Data of Lignin-Derived Precious Metal-Free Electrocatalysts for Anion-Exchange Membrane Fuel Cell Application Authors: Umber Sajjad, Ave Sarapuu, John C. Douglin, Arvo Kikas, Alexey Treshchalov, Maike Käärik, Jekaterina Kozlova, Jaan Aruväli, Jaan Leis, Vambola Kisand, Kaupo Kukli, Dario R. Dekel Contact information: Ave Sarapuu (ave.sarapuu@ut.ee), Kaido Tammeveski (kaido.tammeveski@ut.ee) Institute of Chemistry University of Tartu Ravila 14a 50411 Tartu Estonia This dataset contains the data presented in the figures of published paper "Lignin-Derived Precious Metal-Free Electrocatalysts for Anion-Exchange Membrane Fuel Cell Application " published in ACS Catal. 2024, 14, 9224–9234 (https://doi.org/10.1021/acscatal.4c02136) This dataset contains data for Figures 4-6. The data was collected using Autolab potentiostat/galvanostat PGSTAT30. The working electrode was bulk glassy carbon disk (0.2 cm2) covered with 200 ?g cm?2 of catalyst. The data is given as background-corrected current densities (mA/cm2), that is, the background currents, measured in Ar-saturated solution, have been subtracted from the currents measured in O2-saturated solution.
