Nanochanneling and Local Crystallization Engineering Accelerate Multiphase Single‐Atom Catalysis for Rapid Water Decontamination

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Crystallinity engineering is applied to carbon microspheres for fabricating transition metal single atoms confined in hydrophilic graphitic nanochannels by precisely etching the amorphous carbon realm. This fine‐tuned nanoenvironment enhances tri‐phase mass transfer and optimizes O3 nonradical activation thermodynamics by inducing the bidental “side‐on”
