Synergistic Enhancement of Catalytic Activities in Ligand‐Regulated Carbon Dots‐Ferric Ion Nanozymes via UV‐Enhanced Peroxidase‐Oxidase

). POD-mimicking activity with UV irradiation is 1.93 times that in the dark. Ligand-regulation strategy of CDs-Fe nanozyme based on coordination chemistry offers an idea to design and synthesize high catalytic activities of CDs-metal ions nanozymes.
