Dataset title: Data of one-pot synthesis of Pd nanoparticles supported on carbide-derived carbon for oxygen reduction reaction Authors: Madis Lüsi, Heiki Erikson, Maike Käärik, Helle-Mai Piirsoo, Jaan Aruväli, Arvo Kikas, Vambola Kisand, Jaan Leis, Kaupo Kukli, Kaido Tammeveski Contact information: Heiki Erikson (heiki.erikson@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 "One-Pot Synthesis of Pd Nanoparticles Supported on Carbide-Derived Carbon for Oxygen Reduction Reaction" published in Nanomaterials 2024, 14, 994. https://doi.org/10.3390/nano14120994 This dataset contains data for Figures 5-6. The data was collected using Autolab potentiostat/galvanostat PGSTAT128N controlled with General Purpose Electrochemical System (GPES version 4.9.007) software. The working electrodes was catalyst coated glassy carbon (d=5 mm) electrode. For all supplied electrochemical data the measured currents have been converted from current (A) to current densities (mA/cm2, that is multiplied by 1000 and divided by 0.2 cm2). For Figure 6 the background currents, measured in Ar-saturated solution, have been subtracted, in addition to conversion to current densities.
