Abstract
For many biomedical applications, high-precision CO(2) detection with a rapid response is essential. Due to the superior surface-active characteristics, 2D materials are particularly crucial for electrochemical sensors. The liquid phase exfoliation method of 2D Co(2)Te(3) production is used to achieve the electrochemical sensing of CO(2). The Co(2)Te(3) electrode performs better than other CO(2) detectors in terms of linearity, low detection limit, and high sensitivity. The outstanding physical characteristics of the electrocatalyst, including its large specific surface area, quick electron transport, and presence of a surface charge, can be credited for its extraordinary electrocatalytic activity. More importantly, the suggested electrochemical sensor has great repeatability, strong stability, and outstanding selectivity. Additionally, the electrochemical sensor based on Co(2)Te(3) could be used to monitor respiratory alkalosis.
