Selective non-enzymatic electrochemical detection of dopamine using nickel molybdate nano-dots anchored on CNT fiber microelectrodes.

ABSTRACT: This research demonstrates the hydrothermal synthesis of α-nickel molybdate nano-dots (α-NiMoO₄) and their fabrication on a carbon nanotube fiber (CNTF), serving as an electrocatalyst for non-enzymatic electrochemical sensing of dopamine (DA). Several analytical techniques, such as, scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FTIR), were employed for morphological analysis, crystallinity and elemental composition analysis and characteristic bond vibration analysis of NiMoO₄, respectively. The characterization revealed the presence of ∼10 nm α-NiMoO₄ nano-dots with a significant amount of NiO. The NiMoO₄@CNTF electrode exhibited a remarkable s
