Nano-Based Electrochemical Sensor Studies for Detections of Heavy Metal and Glucose Biomolecule and Its Multiple Applications

The facile green-assisted (Aloe-vera) synthesis of Bi doped MgZrO₄ nanoparticle by solution combustion method. The synthesized nanoparticle was well characterized by Powder X-ray Diffraction (PXRD), Scanning Electron Microscope (SEM), Fourier Transform Infrared (FT-IR) spectroscopy and UV-Visible (UV-Vis) spectral studies. P-XRD analysis reveals the phase formation and crystallite size of synthesized materials was found to be 28 nm using Scherrer’s formula. Energy band gap of synthesized nanomaterial was recorded to be 3.45 eV. The heavy metal ions are severely cause human health, it is vital to develop a simple, sensitive and specific route for their detection in environment and food. The electrochemical sensor detection analysis of prepared NPs was carried out for Mercury heavy metal and Glucose biomolecule in the scan rate of 10 mV/s. The Bi doped MgZrO₄ nanoparticle (5 mol) photocatalyst was synthesized based on the MgZrO₄ nanoparticles by the incorporation of Bi dopant, which showed excellent photocatalytic activity for cationic dye such as methylene blue (MB) under UV-light irradiation at 120 min. The reported results are confirmed that Bi doped MgZrO₄ nanoparticle is suitable candidate for mercury heavy metal sensor detection and photocatalytic applications.
