Photocatalytically Activated Cu‐N1S3 Single‐Atom Nanozyme: Enhancing Enzyme Activities and Antibacterial Synergy for Highly Efficient Fruit Preservation

Advanced Science, EarlyView.
This study presents S‐coordinated Cu single‐atom nanozymes (Cu/CNS) fabricated via mild photocatalytic self‐assembly strategy. The nanozyme exhibits exceptional multi‐enzyme activity and near‐perfect antimicrobial efficacy. Incorporated into chitosan‐gelatin film, it enables pH‐responsive, broad‐spectrum fruit preservation, more than doubling the shelf‐

Sabatier‐Adjusted d‐Band Centers of Scalable Asymmetric Iron Sites toward Dynamic Nonradical Network for Fast Mineralization with Low‐Amount Oxidant

Advanced Science, EarlyView.
Asymmetric iron single‐atom catalysts with Sabatier‐adjusted d‐band centers overcome the inherent limitations of peroxymonosulfate (PMS) activation by establishing a synergistic nonradical pathway network, achieving exceptional pollutant mineralization (≈85%) at only one‐tenth conventional PMS dosage.
