Herein, we report the synthesis of bimetallic PdPt nanoparticles uniformly deposited on thiolated carbon nanotubes (CNTs). Thiol groups were utilized as linkers to secure the PdPt nanoparticles without agglomeration. The structural and surface properties of the prepared CNT-PdPt nanocomposites were characterized in detail, and then the nanocomposites were utilized as electron mediators for the fabrication of highly sensitive hydrazine chemical sensors (see Scheme 1). The as-prepared CNT-PdPt nanocomposite modified glassy carbon (GC) electrode was found to exhibit a linear response to hydrazine in the range 0.55 to 1,200 μM with the detection of 0.28 μM. Moreover, the modified electrode has good anti-interference ability, reusability, and long-term storage stability. |
