Unprecedented peroxidase-mimicking activity of single-atom nanozyme with atomically dispersed Fe-N_x moieties hosted by MOF derived porous carbon.

ABSTRACT: Due to robustness, easy large-scale preparation and low cost, nanomaterials with enzyme-like characteristics (defined as 'nanozymes') are attracting increasing interest for various applications. However, most of currently developed nanozymes show much lower activity in comparison with natural enzymes, and the deficiency greatly hinders their use in sensing and biomedicine. Single-atom catalysts (SACs) offer the unique feature of maximum atomic utilization, providing a potential pathway to improve the catalytic activity of nanozymes. Herein, we propose a Fe-N-C single-atom nanozyme (SAN) that exhibits unprecedented peroxidase-mimicking activity. The SAN consists of atomically dispersed Fe─N_x moieties hosted by metal-organic frameworks (MOF) derived porous carbon. Thanks to the 10
