“…With increasing scan rate, the anodic-peak current for lactate oxidation becomes larger, while the peak potential also shifts to a higher voltage (Figure a). The voltage separation between the anodic peak and the cathodic peak is also found to increase gradually with increasing scan rates, indicating a charge-transfer kinetics limitation that is characteristic of a typical quasi-reversible system . We also compare the cyclic voltammograms with and without the presence of sodium lactate in Figure S4.…”

Electrodeposition of nickel nanoparticles, achieved through potentiostatic amperometry followed by thermal annealing at 200−400 °C, has produced nickel oxide nanoparticles on flexible graphene substrates. Using transmission electron microscopy and depth-profiling X-ray photoelectron spectroscopy, we demonstrate that the resulting NiO x nanoparticles exhibit several Ni oxidation states and a core−shell heterostructure, with a metallic Ni crystalline core and a NiO crystalline shell with a mixed crystalline−amorphous NiOOH/Ni(OH) 2 skin. The composition of the NiOOH/Ni(OH) 2 redox couple relative to NiO is found to vary with the annealing temperature and annealing time. The use of a highly conductive graphene substrate enhances electron transfer. The NiO x nanoparticle samples obtained with selected annealing temperature−time combinations are used for lactate detection, with the best sample showing an excellent linear range of 0.02−65.1 mM, a high sensitivity of 80.0 μA mM −1 cm −2 , and an impressive limit of detection of 0.00015 mM. The NiO x nanoparticle sample is also tested for lactate sensing in an artificial sweat electrolyte, and it exhibits a reduced linear range of 0.02−53.1 mM and a lower limit of detection of 0.00013 mM while maintaining the same high sensitivity of 80.0 μA mM −1 cm −2 . This sensing performance can be optimized by controlling the relative composition NiOOH + Ni(OH) 2 to NiO, with the sample obtained with a higher relative content at a lower annealing temperature found to provide more reactive sites for lactate detection and therefore higher sensitivity.

In the last decades, the idea of green nanotechnology has been expanding, and researchers are developing greener and more sustainable techniques for synthesizing nanoparticles (NPs). The major objectives are to fabricate NPs using simple, sustainable, and cost-effective procedures while avoiding the use of hazardous materials that are usually utilized as reducing or capping agents. Many biosources, including plants, bacteria, fungus, yeasts, and algae, have been used to fabricate NPs of various shapes and sizes. The authors of this study emphasized the most current studies for fabricating NPs from biosources and their applications in a wide range of fields. This review addressed studies that cover green techniques for synthesizing nanoparticles of Ag, Au, ZnO, CuO, Co3O4, Fe3O4, TiO2, NiO, Al2O3, Cr2O3, Sm2O3, CeO2, La2O3, and Y2O3. Also, their applications were taken under consideration and discussed.

“…Also, from a physicochemical perspective, NiO presents other features that make it suitable for consideration regarding sensing applications: (1) ease of obtaining several morphologies, which, generally, affords high surface area and porosity, improving their results; − (2) tunable electrical conductivity by controlling microstructural defects such as vacancies and interstitials; (3) high electrochemical and structural stability of nickel and nickel-based mixed oxides , and; (4) preparation of stable NiO with just one phase, improving the fast transfer of electrons between Ni 2+ and Ni + species when required . Such features make NiO nanomaterials highly promising for applications in supercapacitors, renewable energy, and non-enzymatic glucose sensing . For electrochemical sensors, modified Ni, NiO, and Ni(OH) 2 electrodes commonly provide a well-known redox peak in basic media, which can be related to the oxyhydroxide NiOOH species .…”

Facile Gram-Scale Synthesis of NiO Nanoflowers for Highly Selective and Sensitive Electrocatalytic Detection of Hydrazine

The design and development of efficient and electrocatalytic sensitive nickel oxide nanomaterials have attracted attention as they are considered cost-effective, stable, and abundant electrocatalytic sensors. However, although innumerable electrocatalysts have been reported, their large-scale production with the same activity and sensitivity remains challenging. In this study, we report a simple protocol for the gram-scale synthesis of uniform NiO nanoflowers (approximately 1.75 g) via a hydrothermal method for highly selective and sensitive electrocatalytic detection of hydrazine. The resultant material was characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. For the production of the modified electrode, NiO nanoflowers were dispersed in Nafion and drop-cast onto the surface of a glassy carbon electrode (NiO NF/GCE). By cyclic voltammetry, it was possible to observe the excellent performance of the modified electrode toward hydrazine oxidation in alkaline media, providing an oxidation overpotential of only +0.08 V vs Ag/AgCl. In these conditions, the peak current response increased linearly with hydrazine concentration ranging from 0.99 to 98.13 μmol L–1. The electrocatalytic sensor showed a high sensitivity value of 0.10866 μA L μmol–1. The limits of detection and quantification were 0.026 and 0.0898 μmol L–1, respectively. Considering these results, NiO nanoflowers can be regarded as promising surfaces for the electrochemical determination of hydrazine, providing interesting features to explore in the electrocatalytic sensor field.
