Black Phosphorus Quantum Dots Modified Glassy Carbon Electrode for Electrochemical Detection of Chlorogenic Acid

Abstract In this work, black phosphorus quantum dots (BP QDs) are applied for electrochemical detection of chlorogenic acid, which obtained good results. The BP QDs modified glassy carbon electrode (BP QDs/GCE) sensor exhibit wide linear detection range (0.5−500 µM) and low detection limit (0.13 µM) of chlorogenic acid. The sensor attains good reproducibility, stability, and selectivity for chlorogenic acid detection. Moreover, it was successfully applied to real sample detection, achieving good accuracy. BP QDs as a new electrode modification substrate has a good application prospect in electroanalytical detection.
