ABSTRACT This article is based on Zn‐MOF‐8 and uses a simple thermal synthesis method to prepare nitrogen‐doped mesoporous carbon spheres (NMC), which is then combined with Ti 3 C 2 to prepare NMC/Ti 3 C 2 nanocomposites. It was characterized by SEM, EDS, XPS, FTIR, and electrochemical methods. The NMC/Ti 3 C 2 nanocomposite modified glassy carbon electrode (GCE) was used for sensitive detection of isoquercetin (IQ), achieving a wide linear range of 0.1–100 µM and a low detection limit of 0.073 µM (S/N = 3). The modified electrode also exhibits good selectivity, excellent anti‐interference performance and can be used for actual sample detection.
