“…The formation of a heterojunction interface optimized the chemisorption of HQ and CC, reducing the activation energy for the hydrogen dissociation reaction and facilitating the electrocatalytic oxidation reaction of both molecules [88]. This class of catalysts has also demonstrated sensitive detection capabilities for various molecules, including dopamine [89][90][91][92][93], isoprenaline [94,95], and chloramphenicol [96]. For instance, a selfsupported NiCoP into Ni foam was synthesized using one-step electrodeposition for DA oxidation.…”

Electrochemical sensors have been recognized as crucial tools for monitoring comprehensive chemical information, especially in the detection of a significant class of molecules known as phenolic compounds. These compounds can be present in water as hazardous analytes and trace contaminants, as well as in living organisms where they regulate their metabolism. The sensitive detection of phenolic compounds requires highly efficient and cost-effective electrocatalysts to enable the development of high-performance sensors. Therefore, this review focuses on the development of advanced materials with excellent catalytic activity as alternative electrocatalysts to conventional ones, with a specific emphasis on transition metal-based electrocatalysts for the detection of phenolic compounds. This research is particularly relevant in diverse sectors such as water quality, food safety, and healthcare.

“…Furthermore, recently an effective way to accelerate the kinetics of electrocatalytic reactions and increase the performance of electrocatalysts, especially transition metal-based electrocatalysts, is doping O 2– with P 3– , S 2– , N 3– , and Se 2– in the structure of electrocatalysts that leads to modulating electrocatalytic activity, flexibility, providing more active sites and higher conductivity for them. − Selenide, which has a larger anionic size than others, can provide a suitable band gap and improve the electrochemical activity, and it can also accelerate electron transfer due to its low intrinsic electrical resistance and high electrical conductivity. − …”

In recent years, with the development of nanotechnology, there has been significant progress in the provision and functionalization of nanomaterials based on Ir nanostructures. It is possible to design different Ir-based nanoelectrolysts with improved performance and favorite structure using nanoengineering methods. In this study, porous Ir/Co/NiSe 2 nanocages (NCs) were prepared using the sacrificial template approach, ion exchange strategy, and selenization under heat treatment. The designed Ir/ Co/NiSe 2 NCs were applied to modify the surface of the glassy carbon electrode (GCE) to use as an effective multifunctional electrocatalyst for the O 2 and H 2 evolution reactions (OER and HER) and glucose oxidation in an alkaline medium. The Ir/Co/ NiSe 2 NCs/GCE due to the using the advantages of a threedimensional porous polymetallic hollow nanostructure, including providing high surface area and numerous electrochemical active sites, fast electron/mass transfer, high conductivity, and open channels for effective gas release in the OER and HER reactions, exhibits improved electrochemical performance. The Ir/Co/NiSe 2 NCs/GCE delivered a current density of 100 mA cm −2 at 1.55 V for OER and −0.21 V for HER and determined glucose in the linear ranges of 100.0 nM to 2.0 mM and 2.0−17.0 mM with a limit of detection of 30 nM and sensitivity of 4375.8 and 477.7 μA mM −1 cm −2 , respectively.

“…[16][17][18][19] Reasonable design can not only enable MOF-drived nanomaterials to maintain their porous structure, but also regulate their chemical properties, thus significantly improving their catalytic activity and electrical conductivity. [20][21][22][23][24] Zn-based bimetallic zeolitic imidazole framework (ZIF) is a kind of template MOF with sacrificial properties that can form desired hollow or yolk-shelled structures during pyrolysis and simple pyrolysis can also lead to different scales of carbon pore structures. [25][26][27] In addition, the hybrid nanocages have closely spaced double shell layers: a N-doped microporous carbon inner shell layer derived from ZIF-8 and a Co-modified N-doped mesoporous graphitic carbon outer layer derived from ZIF-67.…”

The design and construction of a promising electrode is attractive for the sensitive and selective detection of hydrazine. Here, hollow CoS2/N-doped mesoporous graphite carbon nanocages (CoS2/HNGC) were synthesized derived from ZIF-8@ZIF-67 by annealing and sulfidation. In situ nitrogen coordination and self-compounding porous carbon with hollow structure can effectively improve electrocatalytic performance and electron transfer rate of catalyst electrode. The sensor has good performance for hydrazine with a wide linear range of 1 μM - 3 mM, high sensitivity of 2384 μA mM-1 cm-2, and detection limit of 0.272 μM (S/N = 3). In addition, the fine selectivity and the application of this sensor in food hydrazine detection suggest that CoS2/HNGC can be used as an efficient electrochemical detection material for hydrazine.
