“…DPV was employed to investigate the electrochemical behaviors of the NH 2 -MIL-53(Al)/PPy nanocomposite in the presence of both Cu 2+ and Pb 2+ , and as a result of the synergistic effects between NH 2 -MIL-53(Al) and PPy, these modified electrodes exhibit suitable sensing performance toward Cu 2+ and Pb 2+ with a range between 1 and 400 μg L –1 and LOD of 0.244 μg L –1 and 0.315 μg L –1 . Importantly, a greater enhancement of the LOD and sensitivity of the NH 2 -MIL-53(Al)/PPy nanocomposite-modified electrode was observed in comparison to those of the individual modified electrode …”

“…Importantly, a greater enhancement of the LOD and sensitivity of the NH 2 -MIL-53(Al)/PPy nanocomposite-modified electrode was observed in comparison to those of the individual modified electrode. 110 Finally, Chen and co-workers prepared a new core−shell structure composite with a conventional conducting polymer, PPy, as the core, and ZIF-8as the shell structure (PPy@ZIF-8), and this composite exhibited very good performance for the electrocatalytic detection of quercetin. The DPV peak current signals are linearly correlated with the quercetin concentrations in a range between 0.01 to 7.0 μM and 7.0 to 150 μM, with a lower LOD equal to 7 nM.…”

Metal−organic frameworks (MOFs), a versatile class of porous materials that exhibit high specific surface areas, controllable structures, and tunable pores, have been identified as a promising platform in the field of electrochemistry in recent years, and researchers have now designed MOFs specific to electrochemical applications. In this review, we describe the recent uses of MOFs and their composites for use in electrochemical sensing, electrocatalysis, and electrochemical energy storage devices (e.g., batteries and supercapacitors), followed by an overview of the remaining challenges and viewpoints for MOF-based materials for these applications.

The human population is generally subjected to diverse pollutants and contaminants in the environment like those in the air, soil, foodstuffs, and drinking water. Therefore, the development of novel purification techniques and efficient detection devices for pollutants is an important challenge. To date, experts in the field have designed distinctive analytical procedures for the detection of pollutants including gas chromatography/mass spectrometry and atomic absorption spectroscopy. While the mentioned procedures enjoy high sensitivity, they suffer from being laborious, expensive, require advanced skills for operation, and are inconvenient to deploy as a result of their massive size. Therefore, in response to the above-mentioned limitations, electrochemical sensors are being developed that enjoy robustness, selectivity, sensitivity, and real-time measurements. Considerable advancements in nanomaterials-based electrochemical sensor platforms have helped to generate new technologies to ensure environmental and human safety. Recently, investigators have expanded considerable effort to utilize polymer nanocomposites for building the electrochemical sensors in view of their promising features such as very good electrocatalytic activities, higher electrical conductivity, and effective surface area in comparison to the traditional polymers. Herein, the first section of this review briefly discusses the most important methods for polymer nanocomposites synthesis, such as in situ polymerization, direct mixing of polymer and nanofillers (melt-mixing and solution-mixing), sol–gel, and electrochemical methods. It then summarizes the current utilization of polymer nanocomposites for the preparation of electrochemical sensors as a novel approach for monitoring and detecting environmental pollutants which include heavy metal ions, pesticides, phenolic compounds, nitroaromatic compounds, nitrite, and hydrazine in different mediums. Finally, the current challenges and future directions for the polymer nanocomposites-based electrochemical sensing of environmental pollutants are outlined.
