Highly Sensitive Hydrazine Chemical Sensor Based on CNT-PdPt Nanocomposites

Figure 6

Amperometric response of the CNT-PdPt held at 0.2 V in 0.1 M PBS (pH 7.4) for successive additions of 1.0 μM hydrazine. For comparison, the amperometric responses of CNT-Pd, CNT-Pt, and commercial Pd/C and Pt/C catalysts are also shown.
