Detection of Hydrazine at MXene/ZIF-8 Nanocomposite Modified Electrode^†

ZIF-8 with excellent chemical and physical properties is a promising material for the field of electrochemical sensing. However, the poor electrical conductivity of ZIF-8 severely limits its electrochemical performance. Here, we report a method that can significantly improve the conductivity of ZIF-8 by intercalating Ti₃C₂T_x MXene as a conductive platform. Benefiting from higher conductivity and unique electrocatalytic activity, the obtained MXene/ZIF-8 nanocomposite presented the worthy analytical performance for hydrazine sensing. The successful fabrication of MXene/ZIF-8 holds great promise for the design of electrochemical sensors, and it is a promising material to promote the development of new electrode materials.
