“…43 Fortunately, electrochemical techniques offer the opportunity for portable, cheap and rapid methodologies. Electrochemical detection techniques also have a series of advantages, 44 such as rapid response, ease of use and low-cost, small-sized commercial detectors, which can satisfy the demands a simple, fast and lowcost method of N 2 H 4 determination. Furthermore, electrochemical methods were favorable for the determination of N 2 H 4 because they were easily automated and showed high sensitivity, great selectivity, time efficiency and reproducibility.…”

A facile, one-pot ultrasonic electrochemical method to synthesize hierarchical cobalt (Co)-nanoflowers on petalage-like graphene (GE) was developed. The hybrid microstructures were successfully evaluated as a new material for highly sensitive determination of hydrazine (N(2)H(4)). Scanning electron microscopic measurements displayed that the synthesized Co-GE exhibited a related hierarchical structure of a petalage-like GE homogeneous distribution as a matrix for the growth of smooth nanosheets-assembled Co nanoflowers. Co-GE was confirmed by energy dispersive X-ray spectrograms. Electrochemical methods were adopted to characterize the sensing properties of Co-GE towards the electrocatalytic oxidation of N(2)H(4) at 0.15 V in 0.1 M pH 7.0 sodium phosphate buffered saline. The sensor displayed a broad linearity of 0.25-370 μM and 370 μM to 2.2 mM with a relatively low detection limit of 0.1 μM (S/N = 3) and a response time of less than 3 s. Furthermore, the sensor showed outstanding sensitivity and reproducibility.

“…The obtained PP-ECMPS were applied as the template for AgNPs growth by chemically reducing AgNO 3 by NaBH 4 [40] (Figure 1b). PtNPs were synthesized through a double-template electrochemical deposition and used as electrochemical interface for electrocatalytic reduction of hydrogen peroxide (H 2 O 2 ) and electrocatalytic oxidation of N 2 H 4 , displaying a fast response (<4 s) and high sensitivity (110 µA mM −1 cm −1 ) [41]. while the sulphonate groups were far away from AuNPs surface.…”

Nanomaterials with unique physical and chemical properties have attracted extensive attention of scientific research and will play an increasingly important role in the future development of science and technology. With the gradual deepening of research, noble metal nanomaterials have been applied in the fields of new energy materials, photoelectric information storage, and nano-enhanced catalysis due to their unique optical, electrical and catalytic properties. Nanostructured materials formed by noble metal elements (Au, Ag, etc.) exhibit remarkable photoelectric properties, good stability and low biotoxicity, which received extensive attention in chemical and biological sensing field and achieved significant research progress. In this paper, the research on the synthesis, modification and sensing application of the existing noble metal nanomaterials is reviewed in detail, which provides a theoretical guidance for further research on the functional properties of such nanostructured materials and their applications of other nanofields.
