Coordination‐Tuned Iridium Single‐Atom Nanozymes Boost Multienzyme Activity for Colorimetric Sensing

Advanced Science, EarlyView.
Breaking the coordination symmetry of Ir single‐atom sites through asymmetric Ir–N3S1 engineering tailors interfacial electron transfer, oxygen activation, and multienzyme‐like catalytic pathways. Operando spectroscopy and theoretical modeling uncover the atomic‐level origin of activity enhancement, providing a strategy for designing multifunctional ...

Asymmetric Single‐Atom Catalysts Govern Diffusible and Non‐Diffusible Non‐Radical Pathways for Selective Degradation of Antibiotic Resistance Genes

Advanced Science, EarlyView.
Asymmetric single‐atom metal‐nitrogen‐carbon catalysts modulate the non‐radical pathway during peroxymonosulfate (PMS) activation. A fundamental contrast was revealed between diffusible singlet oxygen (1O2) and non‐diffusible electron‐transfer pathways (ETP) in antibiotic resistance gene (ARG) degradation.
