Elucidating the mechanism of the structure-dependent enzymatic activity of Fe–N/C oxidase mimics†
Abstract
Herein, we develop an Fe–N/C–CNT nanomaterial with Fe–N3 units as a paradigm for excellent oxidase mimics by theoretical prediction and experimental implementation. The mechanism of the structure-dependent enzymatic activity is systematically investigated and elucidated from the perspective of the different configurations of M–Nx models (x = 0, 3, 4, and 5; M = Fe, Co, and Ni).
