Sensitive detection of H<sub>2</sub>O<sub>2</sub> based on a MWCNTs/Ti<sub>3</sub>C<sub>2</sub> nanocomposite-modified electrode
In this work, MWCNTs/Ti<sub>3</sub>C<sub>2</sub> nanocomposites were synthesized by a convenient method and characterized in terms of structure and properties by SEM, FT-IR, XPS and electrochemical methods. The electrochemical sensor developed with MWCNTs/Ti<sub>3</sub>C<sub>2</sub> nanocomposites exhibits good electrochemical properties. The sensor demonstrates excellent electrocatalytic performance for H<sub>2</sub>O<sub>2</sub> and was used to detect the concentration of H<sub>2</sub>O<sub>2</sub>. The linear range of the sensor was 0.05-1080 μM, with a detection limit of 0.017 μM (S/N = 3). The sensor shows strong anti-interference performance, stability and reproducibility and exhibits good performance in real sample detection.
