Article Synopsis
- Oxygen-containing carbons show potential as effective supports and metal-free catalysts, but it's challenging to identify and adjust the roles of different oxygen functional groups.
- This study focuses on Brønsted acidic oxygen groups by creating a variety of materials and employing advanced techniques like acid-catalyzed chemistry and nuclear magnetic resonance to analyze them.
- Findings reveal that phenolic groups serve as the primary acid site for reactions in gas phase, while carboxylic groups are less acidic than expected due to electron interactions in graphitized carbon structures.
Infrared (IR) spectra of adsorbate vibrational modes are sensitive to adsorbate/metal interactions, accurate, and easily obtainable in-situ or operando. While they are the gold standards for characterizing single-crystals and large nanoparticles, analogous spectra for highly dispersed heterogeneous catalysts consisting of single-atoms and ultra-small clusters are lacking. Here, we combine data-based approaches with physics-driven surrogate models to generate synthetic IR spectra from first-principles.
