Hg<sup>2+</sup> Ions Sensor: Single Walled Carbon Nanotubes Incorporated Zn-Metal Organic Framework
Abstract
<jats:p>In the present work, zinc benzene 1,4 dicarboxylate (ZnBDC) metal organic framework (MOF) and its composite with single-walled carbon nanotubes (SWNTs), we called as SWNTs@ZnBDC, has been synthesized by traditional solvothermal method. The synthesized materials have been evaluated withvarious techniques such as Fourier transform infrared spectroscopy, X-ray diffraction (XRD), thermogravimetric-differential thermal analysis, Brunauer–Emmett–Teller surface area analysis, cyclic voltammetry, and electrochemical impedance spectroscopy. The sensor has been fabricatedby depositing SWNTs@ZnBDC MOF on a glassy carbon electrode (GCE). The SWNTs@ZnBDC/GCE electrode shows excellent sensing behaviour in terms of selectivity towards Hg<jats:sup>2+</jats:sup> ions only at pH = 5 and does not show any sensing response towards Pb<jats:sup>2+</jats:sup>, Cr<jats:sup>2+</jats:sup>, Cd<jats:sup>2+</jats:sup>,Cu<jats:sup>2+</jats:sup>, and Ni<jats:sup>2+</jats:sup> ions at a concentration of 1 <jats:italic>μ</jats:italic>M. For the Hg<jats:sup>2+</jats:sup> ions, the sensor shows a high sensitivity of 0.86 <jats:italic>μ</jats:italic>A/nM with a limit of detection of 6.74 nM and a limit of quantification of 5 nM.</jats:p>
