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.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
