摘要

The current study aims to develop the electrochemical sensor based on the rarely studied metalmolybdate. Based on this view, we have developed a novel yttrium molybdate (YMoO 4 ) nanosheets(NSs) using wet-chemical method. Further, the conductivity of YMoO 4 NSs was improved by integrationwith functionalized carbon nanofiber (f-CNF) through a simple ultrasonication method. As-preparedYMoO 4 and YMoO 4 /f-CNF composite was systematically characterized by various spectroscopictechniques including XRD, RAMAN, and HR-TEM analysis. From the analysis, the successfulintegration of YMoO 4 with f-CNF was scrutinized. In addition, the electrocatalytic behavior ofYMoO 4 /f-CNF nanocomposite was investigated by the electrochemical detection of bisphenol-A (BPA)using cyclic voltammetry and differential pulse voltammetry techniques. As we expected, YMoO 4 /f-CNF modified glassy carbon electrode (GCE) achieved a low detection limit of 0.01 μM and linearresponse range of 0.1 - 1318 μM towards the detection of BPA. From the above results clearly, evidencedthat the YMoO 4 /f-CNF nanocomposite was an efficient electrode material for the determination of BPAin real sample analysis.
