Single-atom catalysts, particularly metal/nitrogen-doped carbons, have become a versatile platform for fine-tuning electronic interactions with reactants and controlling thermodynamic selectivity. Here, the authors show that the catalytic ozonation activity of single-atomic Co–N₄ sites can be electronically modulated by adjusting the density of Co nanoparticles on the carbon matrix.
