Amperometric hydrazine sensor based on the use of Pt-Pd nanoparticles placed on reduced graphene oxide nanosheets

Recent developments in electrochemical sensors for detecting hydrazine with different modified electrodes

“…Also, satisfactory values for detection of HZ in water sample were observed which conrm practical application of the sensor toward HZ detection. 82 Based on the studies conducted so far, bimetallics catalyst has been remarkably considered because of the enhanced catalytic activities and more reasonable stability in comparison to the mono-metallica. For example, Zhang and Zheng dealt with the preparation of various Au@Ni bimetallic structures decorated GO via setting Ni and Au mass ratio.…”

Mechanism of hydrazine oxidation at Palladium electrodes: Long-lived radical di-cation formation

“…Ghasemi et al [10] fabricated an amperometric nanosensor with platinum-palladium nanoparticles decorated reduced graphene oxides, and it exhibited an excellent sensing performance with a linear response range between 0.007 -5.5 mM and a 1.7 μM detection limit. Notwithstanding the great progress made empirically, the understanding of the mechanism of the four electron, four/five proton hydrazine oxidation remains challenging, but vital to provide generic guidance for catalyst design.…”

Self-assembled ZnO microspheres coated with carbon dot-doped CoNi LDH wrinkled films as electrochemical sensors for highly sensitive detection of hydrazine

“…The first step is slow one electron transfer, and the second step is fast three electron transfer, which is consistent with the reported literature (Scheme 2). 56,57…”

“…The rst step is slow one electron transfer, and the second step is fast three electron transfer, which is consistent with the reported literature (Scheme 2). 56,57 Performance study of hydrazine electrochemical sensors An electrochemical sensing platform for hydrazine was constructed by an amperometric method based on ZnO@CoNi LDH-NCDs. To achieve the best sensing performance, the effects of pH and working potential on the sensor were investigated.…”
