Obtaining N-Enriched Mesoporous Carbon-Based by Means of Gamma Radiation Kamedulski, Piotr Abdelkader Fernández, Víctor Karim Carbon materials Mesoporous activated carbons Gamma irradiation Heteroatoms Nitrogen In this paper, we present the results of the gamma irradiation method to obtain N-doped mesoporous activated carbons. Nitrogen-enriched mesoporous carbons were prepared from three chosen commercial activated carbons such as Carbon Black OMCARB C-140, KETJENBLACK EC-600JD and PK 1-3 Norit. HRTEM, SEM, Raman spectra, elemental analysis, XPS studies and widely approved N2 adsorption–desorption measurements allowed us to evaluate the effectiveness of N atom insertion and its influence on the BET surface area and the pore structure of modified carbons. The obtained materials have an exceptionally high N content of up to 3.2 wt.%. Additionally, selected N-doped activated carbons were fully characterized to evaluate their applicability as carbon electrode materials with particular emphasis on Oxygen Reduction Reaction (ORR). The proposed method is a relatively facile, efficient and universal option that can be added to the already known methods of introducing heteroatoms to different carbons. 2022-10-17T12:25:30Z 2022-10-17T12:25:30Z 2022-09-12 journal article Kamedulski, P...
