In this approach, we develop noble electrochemical sensor probe using binary Yttrium oxide/Cobalt oxide nanomaterials conjugated with functionalized-multiwalled carbon nanotube (f-MWCNT) for the sensing of Thiourea (TU; Thiocarbamide 2-Thiourea; CH4N2S). Y2O3/Co3O4 functionalized MWCNT nanocomposites have been prepared using direct solid state chemical technique and characterized using various techniques. Additionally, powder XRD, UV/vis., SEM, BET, and FTIR were used to assess the crystallinity, band-gap energy, surface morphology, surface area, and functional properties of the synthesized Y/Co-MWCNT NC materials respectively. The electrochemical activity of the proposed sensor was further assessed through electrochemical EIS, LSV, and CV. The glassy carbon electrode (GCE) was constructed using the prepared Y/Co-MWCNT NCs by incorporating 5% Nafion to fabricate the electrode for the examination of electrochemical sensor analyses and performances in the phosphate buffer solution (PBS). The modified electrode was successfully detected TU in PBS at a pH of 6.5, showcasing remarkable electrocatalytic activity. The recommended sensor probe (Y/Co-MWCNT NCs/GCE) demonstrated linearity within a concentration range of 7.0 x 10 -10- 3.1 x 10-9 molL-1, a detection limit of 2.8 x 10- 8 mmolL-1 and sensitivity of 5.85 x 10-3 mu AmM-1cm-2. The selectivity of the newly prepared probe for thiourea detection was also evaluated in the presence of various chemicals and interfering agents. The spiked real water samples demonstrated an impressive recovery value when employing the proposed method. A new route is introduced utilizing binary metal oxides intercalated functionalized MWCNTs nanocomposites through reliable electrochemical approaches, aimed at enhancing safety in ecological and environmental domains on an extensive measure.
