Boron-doped Fe-N-C single-atom nanozymes specifically boost peroxidase-like activity

Boron-doped Fe-N-C single-atom nanozymes with an intrinsic charge transfer achieve the significantly enhanced peroxidase-like activities and selectivities, which opens a new route in the rational design of more advanced nanozymes at the atomic scale and bridge the gap between nanozymes and natural enzymes.
