“…In analyzing nitrite, a wide number of evidence is available that has developed during the past few years. For example, Ding and co‐workers [187] converted eggshells into functioning materials following a turning waste‐in treasure strategy. Since eggshells possess a porous hierarchical structure, they were used as a template for the synthesis of AuNPs.Au‐CaCO 3 was envisioned without adding any toxic reagents or organic solvents.…”

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.

In addition, precious metals (Au, 16 Pt, 1 Pd, Reduced graphene oxide (rGO), a derivative of graphene, has attracted tremendous attention due to its properties, such as its high surface area, and its excellent electrochemical properties. Chemical reduction is one of the preferred methods for preparing rGO from graphene oxide.…”

Widely presented nitrite in drinking water, food and even physiological system endangers human health. Here,bare gold nanoparticles functionalized Zr-based metal-organic framework modified reduced graphene oxide (GNPs/UiO-66-NH 2 /rGO) nanocomposites were prepared by hydrothermal method. This experiment studies the morphology, composition, structure and electrochemical behavior of the sensor. The experimental results show that the sensor has a peak potential of 0.9 V, the concentration range of NO 2 À is 5.0 μM to 768 μM, the linear regression equation of the calibration curve is I pa = 0.3646 + 0.00642 C (R 2 = 0.9998), and the LOD is as low as 3.7 μM (S/N = 3). Therefore, an electrochemical sensor platform for trace detection of NO 2 À was successfully constructed.
