However, feasible synthesis methods are necessary to stabilize single metal atoms, increase catalyst loadings and scale up the synthesis. Due to its sluggish kinetics, the oxygen reduction reaction (ORR) is the main source of irreversibility in proton exchange membrane fuel cells (PEMFC). The most promising candidates to replace Pt-based catalysts for the ORR in fuel cells are the so-called Fe-N/C catalysts. These catalysts display high ORR activity in acidic and alkaline electrolytes. In this work, we propose a laser-driven pyrolysis approach to generate Fe-N/C SACs that involves decomposition of aerosolized iron-phthalocyanines. The resulting catalyst displays ORR activity in acidic and alkaline electrolytes, with competitive half-potential and kinetic current density values in comparison with state-of-the-art electrocatalysts. info:eu-repo/grantAgreement/ES/AEI/CEX2023-001286-S info:eu-repo/grantAgreement/ES/AEI/PID2020-114926RB-I00 info:eu-repo/grantAgreement/ES/UZ-DGA/T57-23R info:eu-repo/grantAgreement/ES/MICINN/CNS2022-135911 info:eu-repo/grantAgreement/ES/MICINN/PID2020-115159GB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2020-116712RB-C21 info:eu-repo/semantics/openAccess by-nc https://creativecommons.org/licenses/by-nc/4.0/deed.es 13.2 2024 ENGINEERING, ENVIRONMENTAL 3 / 83 = 0.036 2024 Q1 T1 ENGINEERING, CHEMICAL 8 / 176 = 0.045 2024 Q1 T1 2.696 2024 Chemical Engineering (miscellaneous) 2024 Q1 Industrial and Manufacturing Engineering 2024 Q1 Environmental Chemistry 2024 Q1 Chemistry (miscellaneous) 2024 Q1 20.6 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Tolosana-Moranchel, Álvaro García, Álvaro Rojas, Sergio Bartolome, Fernando (orcid)0000-0002-0047-1772 Pakrieva, Ekaterina Universidad de Zaragoza Simonelli, Laura Martinez, Gema (orcid)0000-0001-7872-6301 Hueso, Jose L.
