Although a number of nanozymes have been developed, it is still difficult to develop single-component nanozyme with overall high multienzyme-like activities. In this study, the nanosized metal-organic frameworks (nano-MOFs) FePCN (PCN stands for porous coordination network) was synthesized by inte-grating zirconium and iron ions with different catalytic property on single-component MOFs and exhib-ited superior intrinsic multienzyme-like activities, namely oxidase-, peroxidase-and phosphatase-mimicking activity. The catalytic active sites of oxidase-and peroxidase-, and phosphatase-like activity of FePCN were Fe-centers and Zr-O clusters, respectively. Based on the intrinsic oxidase-like activity and the similarity of molecular structures between cytochrome P450 oxidase (CYP) cofactors and the organic linker in FePCN, FePCN exhibited high CYP-like activity to catalyze the oxidation of hypotensive drug 1,4-dihydropyridine (1,4-DHP) into diethyl 2,6-dimethylpyridine-3,5-dicarboxylate (DDPD) and the yield of DDPD reached over 80%. Moreover, as peroxidase-and phosphatase-mimics, FePCN was successfully applied to detecting H2O2 under neutral condition and catalyzing the dephosphorylation of adenosine triphosphate (ATP), respectively. This study provides a feasible way for rational design one component nanomaterials as multienzyme-mimics. (C) 2021 Elsevier Inc. All rights reserved.
