Název v původním jazyce

Tin oxide nanoparticles-coated cathode for the detection of aqueous urea using compost-based microbial fuel cell configuration

Popis výsledku v původním jazyce

In the present work, the cathode of the fabricated microbial fuel cell (MFC) was optimised with a coating of tin oxide (SnO2) nanoparticles, and subsequently the MFC was used to develop a urea sensor; application of the MFC configuration for urea sensing has been reported for the first time. Chronoamperometry technique was employed for the coating of SnO2 on the copper (Cu) electrode used as an electron acceptor on the cathode side of the MFC. X-ray diffraction (XRD) was used to study the structure, field emission-scanning electron microscopy (FE-SEM) was used to study the morphology, and energy-dispersive X-ray spectroscopy was used to study the elemental composition. Electrochemical analysis was performed using cyclic voltammetry, linear sweep voltammetry, and electrochemical impedance spectroscopy. Current-voltage (I-V) analysis was done to generate polarisation curves in the MFC, which exhibited better results with SnO2-coated Cu-cathode in comparison to the bare Cu-electrode. Additionally, the MFC device fabricated with the SnO2-coated Cu-cathode exhibited better energy generation in comparison to the bare Cu-electrode, highlighting the application of the compost-based MFC as a multifunctional device.
