Selective and sensitive detection of 4-nitrophenol in ecological water samples based on terbium tungstate anchored with graphitic nitride
In this work, the Tb2(WO4)3/C3N4 composite is for the electrochemical sensing of 4-nitrophenol (4-NP). Tb2(WO4)3 was prepared by hydrothermal method. Tb2(WO4)3 homogeneously functionalized with the g-C3N4 by a noncovalent π–π interaction. Besides, field emission scanning electron microscopy, x-ray diffraction studies, and energy-dispersive x-ray spectroscopy were utilized to characterize the prepared materials. Cyclic voltammetry and amperometry techniques were used to investigate the electrocatalytic behavior of prepared electrode materials. The reduction in 4-NP exhibits high electrocatalytic activity, with best at working voltage with a linear response range of up to 1200 μM. Moreover, the SPCE/C3N4/Tb2(WO4)3 electrode exhibited a detection limit and sensitivity of 0.23 μM and 1.72 μAμM−1 cm−2, respectively. The electrode provides a workable platform for the analysis of 4-NP in water samples and is highly reproducible and stable.
