A novel, sensitive Ti 3 C 2 MXene/Co 3 O 4 /carbon nanofibers (Ti 3 C 2 MXene/Co 3 O 4 /CNFs) composite was synthesized via a HF exfoliating Ti 3 AlC 2 strategy, followed by doping Co 3 O 4 and Ti 3 C 2 MXene into the CNFs via a combination electrospinning and thermal annealing process. Ti 3 C 2 MXene/Co 3 O 4 /CNFs composite exhibits higher catalytic effect, conductivity, chemical stability, and electrochemical performance than Co 3 O 4 and Ti 3 C 2 MXene in electrochemical impedance, differential pulse stripping voltammetry, chronocoulometry, and cyclic voltammetry tests. This Ti 3 C 2 MXene/Co 3 O 4 /CNFs hybrid modified electrode provides fast analysis of 4-aminophenol (4-AP) with ultrahigh sensitivity, enhanced reproducibility and strong anti-interference capability. Furthermore, the level of 4-AP was quantified by this electrode with a wide linear range from 0.5 to 150 μM (R2 > 0.99) and a low detection limit about 0.018 μM was achieved. Finally, the fabricated electrode was used for fast and sensitive analysis of 4-AP spiked in tap water and blood serum samples. This work presents the new Ti 3 C 2 MXene/Co 3 O 4 /CNFs electrode provides a platform for 4-AP monitoring and has the advantages of high selectivity, accuracy, simplicity, and rapid analysis. [Display omitted] • A novel Ti 3 C 2 MXene/Co 3 O 4 /CNFs based electrochemical sensor was fabricated for sensing of 4-AP. • The electrochemical sensor showed excellent sensitivity, repeatability, reproducibility, and selectivity. • Lower limit of detection of 4-AP was found to be 0.018 μM. • This propose sensor successfully determined 4-AP in real samples.
