The incorporation of nitrogen enhances the hydrophilicity of typically rather nonpolar carbon‐based materials but the molecular understanding of water chemical configuration in such porous materials remains incomplete. Water adsorption on nitrogen‐containing nanoporous carbon surfaces is governed by a subtle balance between water–water and water–surface hydrogen bonding interactions, which together determine the water structures formed and their stability. In this work, in situ Scanning Transmission X‐ray microscopy performed on individual nanoporous carbon particles under a humid atmosphere is used to elucidate the interactions between nitrogen‐containing carbon surfaces and water molecules. The hydrogen bonding of water is found to be nonuniform within the particles and to depend on the nanopore size and the chemical bonding of nitrogen atoms. The nature of the nitrogen sites interacting with water is further characterized by resonance inelastic X‐ray Scattering and near ambient pressure X‐ray Photoelectron Spectroscopy. This study provides new perspectives on water interaction when confined in nanoporous nitrogen‐rich carbons. hydrogen bonding near ambient pressure XPS nitrogen doping spectromicroscopy surface chemistry article Amargianou, Faidra Author aut Helmholtz‐Zentrum Berlin für Materialien und Energie GmbH Albert‐Einstein‐Straße 15 12489 Berlin Germany Faculty of Mathematics and Natural Sciences TU‐Berlin, Hardenbergstr. 36 10623 Berlin Germany Förster, Jan‐David Author aut Multiphase Chemistry Department Max Planck Institute for Chemistry Hahn‐Meitner‐Weg 1 55128 Mainz Germany Pöhlker, Christopher Author aut Multiphase Chemistry Department Max Planck Institute for Chemistry Hahn‐Meitner‐Weg 1 55128 Mainz Germany Rauch, Thomas Guy Author aut Helmholtz‐Zentrum Berlin für Materialien und Energie GmbH Albert‐Einstein‐Straße 15 12489 Berlin Germany Wong, Deniz Author aut Helmholtz‐Zentrum Berlin für Materialien und Energie GmbH Albert‐Einstein‐Straße 15 12489 Berlin Germany Schulz, Christian Author aut Helmholtz‐Zentrum Berlin für Materialien und Energie GmbH Albert‐Einstein‐Straße 15 12489 Berlin Germany Seidel, Robert Author aut Helmholtz‐Zentrum Berlin für Materialien und Energie GmbH Albert‐Einstein‐Straße 15 12489 Berlin Germany Weigand, Markus Author aut Helmholtz‐Zentrum Berlin für Materialien und Energie GmbH Albert‐Einstein‐Straße 15 12489 Berlin Germany Oschatz, Martin Author aut Institute for Technical Chemistry and Environmental Chemistry Friedrich‐Schiller‐University Jena Philosophenweg 7a 07743 Jena Germany Center for Energy and Environmental Chemistry Jena (CEEC Jena) Philosophenweg 7a 07743 Jena Germany Helmholtz Institute for Polymers in Energy Applications Jena (HIPOLE Jena) Lessingstraße 12–14 07743 Jena Germany (DE-588)1070230448 Petit, Tristan Author aut Helmholtz‐Zentrum Berlin für Materialien und Energie GmbH Albert‐Einstein‐Straße 15 12489 Berlin Germany Friedrich-Schiller-Universität Jena Chemisch-Geowissenschaftliche Fakultät host institution his 34, 2024:46:2406528<1 Technische Universität Ilmenau, Universitätsbibliothek Advanced functional materials 1616-3028 dbt_mods_00047842 https://www.db-thueringen.de/receive/dbt_mods_00064356 object in context https://www.db-thueringen.de/servlets/MCRFileNodeServlet/dbt_derivate_00066419/ADFM_ADFM202406528.pdf raw object https://www.db-thueringen.de/rsc/thumbnail/dbt_mods_00064356.png preview https://www.db-thueringen.de/receive/dbt_mods_00064356 uri
