MXene/NiCu-MOF//AC Nanocomposite Electrode: A Dual-Functional Platform for Energy Storage and Real-Time Monitoring of Monosodium Glutamate Based Sensors

Monosodium glutamate (MSG), also known as sodium glutamate, is a widely used food additive in commercial foods, and controlling its level is essential for ensuring food safety and quality. For the detection of MSG, the hydrothermal approach is used to synthesize both MXene and NiCu-MOF. Scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy were manipulated to examine the composite morphology, structure, and composition. The MXene/NiCu-MOF electrode displayed an exceptional specific capacity of 277 Cg −1 at a scanning speed of 1.3 mVs −1 . The MXene/NiCu-MOF//AC electrode exhibited an exceptional (Cs) of 271.64 Cg −1 at 2 Ag −1 when employed in a supercapattery. The device demonstrated excellent performance, attaining a (P d ) of 1946.21 W kg −1 and (E d ) of 37.17 Wh kg −1 . Furthermore, MXene/NiCu-MOF//AC demonstrated exceptional capacity retention of 81% after 5,000 cycles in the reliability test. The MSG was utilized as a glassy carbon electrode which was enhanced with gold nanoparticles. The current detection technique implemented NiCu- MOF/MXene as a conductive matrix, with the use of an anti-glutamate antibody. The correlation remained stable from 0.05 to 200 μM detection range. The multipurpose MXene/NiCu-MOF nanocomposite electrode material opens up possibilities for developing novel hybrid devices in energy harvesting.
