“…β‐cyclodextrin‐capped AuNPs were synthesized in a colloidal form and finally drop casted on GCE to get the desired tool with anodic peak at 0.79 V. It is superior not only because of its outstanding LOD value of 14 nM, but also for ecofriendly synthesis without any stabilizer, reducing agent or harsh reagents. Most recently, capping of AuNPs by CDs was done by Feng and co‐workers [191] and arranged on MXenes. In this green synthesis method for manufacturing nitrite sensors, xylene‐based carbon quantum dots were used as reducing agent and MXenes acted as matrix.…”

Nitrite is one of the abundant toxic components existing in the environment and is likely to have a great potential to affect human health badly. For that reason, it has become crucial to build a reliable nitrite detection method. In recent years, several nitrite monitoring systems have been proposed. Compared with traditional analytical strategies, the electrochemical approach has a bunch of advantages, including low cost, rapid response, easy operation, simplicity, etc. In this case, noble metal nanomaterials, especially Au‐based nanomaterials, have attracted attention in electrode modification because of higher catalytic activity, facile mass transfer, and broad active area for determining nitrite. This review is based on the state‐of‐the‐art, which includes a variety of nanomaterials that have been coupled with gold nanoparticles (AuNPs) for the creation of nanocomposites, and the construction as well as development of electrochemical sensors for nitrite detection over the last few years (2016‐2022). A background study on synthesizing different morphological AuNPs and nanocomposites has also been introduced. The fabrication methods and sensing capabilities of modified electrodes are given special consideration.

“…Han et al proposed detection of nitrite based on rose-like AuNPs/MoS 2 /graphene composite. Feng et al prepared a Au@Carbon quantum dots–MXene nanocomposite for sensitive detection of nitrite [ 28 ]. These materials show their unique advantages in the field of electrochemistry, and, to the best of our knowledge, these AuNPs integrated with CS and Ti 3 C 2 have not yet been reported on in use for an electrochemical nitrite sensor.…”

Nitrite is common inorganic poison, which widely exists in various water bodies and seriously endangers human health. Therefore, it is very necessary to develop a fast and online method for the detection of nitrite. In this paper, we prepared an electrochemical sensor for highly sensitive and selective detection of nitrite, based on AuNPs/CS/MXene nanocomposite. The characterization of the nanocomposite was demonstrated by scanning electron microscopy (SEM), a transmission electron microscope (TEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). Under the optimized conditions, the fabricated electrode showed good performance with the linear range of 0.5–335.5 μM and 335.5–3355 μM, the limit of detection is 69 nM, and the sensitivity is 517.8 and 403.2 μA mM−1 cm−2. The fabricated sensors also show good anti-interference ability, repeatability, and stability, and have the potential for application in real samples.

“…Numerous methods have been used to develop carbon-supported nanocomposites, most notably sol-gel [19] microwave (MW) assisted [20], sonochemical [21], electrochemical [22], and hydrothermal (HT) [23]. Among them, the electrochemical technique is a promising one due to several merits, including shorter fabrication time, uniform and desired thickness of film deposition, and higher stability [24].…”

Carbon-based nanocomposites have developed as the most promising and emerging materials in nanoscience and technology during the last several years. They are microscopic materials that range in size from 1 to 100 nanometers. They may be distinguished from bulk materials by their size, shape, increased surface-to-volume ratio, and unique physical and chemical characteristics. Carbon nanocomposite matrixes are often created by combining more than two distinct solid phase types. The nanocomposites that were constructed exhibit unique properties, such as significantly enhanced toughness, mechanical strength, and thermal/electrochemical conductivity. As a result of these advantages, nanocomposites have been used in a variety of applications, including catalysts, electrochemical sensors, biosensors, and energy storage devices, among others. This study focuses on the usage of several forms of carbon nanomaterials, such as carbon aerogels, carbon nanofibers, graphene, carbon nanotubes, and fullerenes, in the development of hydrogen fuel cells. These fuel cells have been successfully employed in numerous commercial sectors in recent years, notably in the car industry, due to their cost-effectiveness, eco-friendliness, and long-cyclic durability. Further; we discuss the principles, reaction mechanisms, and cyclic stability of the fuel cells and also new strategies and future challenges related to the development of viable fuel cells.
