摘要
S-doped carbon materials have recently attracted much attention as electrode materials for electrocatalysis and sensors applications. Herein, we report a facile route for the preparation in situ of flake S-doped carbon nanomaterial by using plate-like sulfur-containing metal-organic frameworks (MOFs) as a pyrolytic precursor without additional carbon and sulfur sources. The resultant MOFs-derived carbon (denoted as PSMC) was further characterized and analyzed by scanning electron microscope, transmission electron microscope, X-ray diffraction, X-ray photoelectron spectroscopy and Raman spectroscopy. Then a highly sensitive electrochemical sensor for selective determination of Hg (II) was achieved by designing PSMC as the active electrode material. The sensitivity of Hg (II) at the sensor is 2.12[Formula: see text][Formula: see text]A[Formula: see text]ppb[Formula: see text][Formula: see text]cm[Formula: see text] according to the slope of the calibration plot and electrode area. Finally, the PSMC-based sensor was proved feasible in river water sample analyses. This work may also provide a valuable clue for the preparation of flake S-doped carbon sensing material as a new application of MOFs-based materials.¡abs¿
