“…The electrochemical characteristics of the MgNiO 2 CFs modified electrode towards the detection of Hg 2+ ions were investigated using cyclicvoltammetry (CV). A three-electrode system was utilized with MgNiO 2 CFs as the working electrode, Ag/AgCl as the counter electrode, and Pt as the reference electrode [ 49 ]. The target electrolyte was prepared by dissolving different concentration of Hg 2+ ions (1–100 μM) in phosphate buffer solution (PBS, pH = 7.0), and the CV plots were measured at a scan rate of 50 mV/s, as shown in Figure 7 a.…”

A simple hydrothermal synthesis approach was used to synthesize porous MgNiO2 Chrysanthemum Flowers (CFs) nanostructures and applied as a sensing electrode for quick detection of hazardous mercury (Hg2+ ions). The morphological, structural, and electrochemical properties of MgNiO2 CFs were investigated. The morphological characteristic of MgNiO2 CFs, with a specific surface area of 45.618 m2/g, demonstrated strong electrochemical characteristics, including cations in different oxidation states of Ni3+/Ni2+. Using a three-electrode system for electrochemical detection, the MgNiO2 CFs based electrode revealed a good correlation coefficient (R2) of ~0.9721, a limit of detection (LOD) of ~11.7 μM, a quick response time (10 s), and a sensitivity of 8.22 μA∙μM−1∙cm−2 for Hg2+ ions over a broad linear range of 10–100 μM. Moreover, the selectivity for Hg2+ ions in tap water and drinking water was determined, and a promising stability of 25 days by MgNiO2 CFs electrode was exhibited. The obtained results indicate that the developed MgNiO2 CFs are a promising electrode for detecting hazardous Hg2+ ions in water and have the potential to be commercialized in the future.

“…30 Accordingly, the shifts of the charge carriers with respect to the Fermi level may be related to presence of defects at the MgO thin-films, 27 which display different properties still not completely understood. 31 Defects can be formed either spontaneously during the growth process (magnesium deposition under an oxygen background pressure) or intentionally by bombarding the surface with electrons. 32 Furthermore, due to the strong basicity of MgO surfaces, the reactivity of defects can be controlled under CO 2 33,34 and water conditions.…”
