The detection of pollutant and toxic gases has attracted extensive attention due to the growing environmental issues. In the present investigation, free-based tetraphenyl porphyrin (TPP) and iron tetraphenyl porphyrin (FeTPP) are used to functionalize thermally reduced graphene oxide (rGO) and further used for the detection of carbon monoxide (CO). TPP and FeTPP functionalized rGO (FeTPP@rGO) sensors are fabricated on a glass substrate with thermally coated copper electrodes. The materials are characterized with X-ray diffraction (XRD), Fourier transforms infrared (FTIR) spectroscopy, Raman spectroscopy, UV–visible spectroscopy, atomic force microscopy, scanning electron microscopy, and energy dispersive spectroscopy. The current–voltage (I–V) characteristics have also been studied to demonstrate the operation of the device. In addition, the FeTPP@rGO device shows high sensitivity toward the detection of CO. By testing in the chemiresistive sensing modality, the as-fabricated device shows good response and recovery of 60 s and 120 s, respectively, with a low detection limit of 2.5 ppm. © 2023, The Author(s).

Due to industrialization, the presence of heavy metal ions in various sources of drinking water causes damage to the ecosystem. Determination of heavy metal ions is still arduous due to their toxicity and carcinogenic behavior to humankind. The present investigation deals with the development of a novel ultrasensitive electrochemical sensor for the detection of lead (Pb2+) from pesticide and fruit core. Repetitive laboratory-scale aqueous samples have been tested to validate all sensing parameters, it exhibited highly selective behaviour towards Pb2+. Hydrothermally synthesized Yttrium Benzenetricarboxylate (Y-BTC) has been characterized by means of structural, morphological, electrochemical and spectroscopic characterizations and utilized as a sensing material. Y-BTC sensor’s differential pulse behavior shows affinity towards Pb2+, a detailed sensing mechanism further illustrated by XPS studies, DLS measurements, deformation studies by photoluminescence spectra, and charge transfer resistance obtained from EIS data. The developed Y-BTC sensor showcased an excellent picomolar detection limit of 1 pM. Reliability of developed sensor was confirmed by evaluation of sensitivity (4.4 μA M−1), selectivity (towards Pb2+), repeatability and reproducibility. The proposed sensor would play a vital role in monitoring human health in the upcoming days. © 2023 The Electrochemical Society ("ECS"). Published on behalf of ECS by IOP Publishing Limited.

Voltammetric determination of toxic Cd2+, Pb2+, and Hg2+ metal ions using Cr-BDC/GCE (chromium-benzenedicarboxylates/ Glassy Carbon Electrode) electrochemical sensor has been investigated. Cr-BDC (chromium-benzenedicarboxylate ) metal-organic framework was synthesized by using the facile hydrothermal technique and its efficacy investigated using P-XRD, FTIR, RAMAN, AFM, FE-SEM, and BET, while the electrochemical performance was investigated by CV and EIS technique. The determination capability of Cr-BDC/GCE as an electrochemical sensor has been investigated by DPASV technique. Effective Voltammetric parameters such as pH of buffer solution, pre-accumulation potential, and pre-accumulation time have been optimized to enhance the sensitivity, selectivity, LOD, repeatability, reproducibility, and stability of the sensor. The proposed Cr-BDC/GCE electrochemical sensor exhibits a sensitivity of 16.55, 3.45, and 3.33 μA M-1 and LOD of 0.186, 0.116, and 0.124 nM for Cd2+, Pb2+ and Hg2+ ions, respectively. Moreover, the sensor exhibited good selectivity, reproducibility, repeatability and stability. The sensor also exhibited good recovery and low RSD values for actual tap water samples. Interaction mechanism of Heavy Metal Ions with the Cr-BDC/GCE evidenced by CV and FTIR confirms the surface adsorption-controlled reaction. These findings suggest that the Cr-BDC/GCE platform is well-suited to serve as a next-generation electrochemical sensor for detecting alcohol, ketone, hydrocarbons, medicines, etc. © 2023 The Electrochemical Society ("ECS").

High performance gas sensors are urgently needed for the welfare of modern society. A challenge for sensors to detect analytes is its high response time. Herein, a carbon monoxide sensor has been fabricated using a NiO-based metal–organic framework(MOF)/reduced graphene oxide(rGO) composite. Synthesis of NiO-MOF and NiO-MOF/rGO were carried out by hydrothermal method. All the synthesized materials were multi parametrically tested by X-ray Diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR), Raman spectroscopy, UV–visible spectroscopy, Atomic Force Microscopy (AFM), Field emission scanning electron microscopy (Fe-SEM), Current-Voltage characteristics (I-V), Brunauer-Emmett-Teller analysis (BET), etc. for their structural, spectroscopic, morphological, electrical, and surface properties respectively. The NiO-MOF/rGO based chemiresistive sensor fabricated on a glass substrate with a 100 µm gap through a shadow mask using an e-beam evaporator is stable up to 30 days and shows a selective response towards CO with excellent response and recovery, i.e. 30 s and 70 s respectively at 25 ppm. © 2023 Elsevier Ltd

Sensing and monitoring nitrogen dioxide (NO2) gas is essential, due to its adverse effect on humans and the environment. However, conventional NO2 gas-sensing materials have limitations like elevated temperature operations, lower response, and low selectivity. Herewith, ceria nano-cube decorated reduced graphene oxide nanosheets (CeO2@rGO) were synthesized by a hydrothermal process, and as-synthesized products were characterized by various methods, viz. XRD, FE-SEM, FTIR, Raman spectrometer, BET, and IV characteristics. Afterwards, CeO2@rGO flexible gas sensor was fabricated by drop-cast technique, which is utilized for real-time monitoring of NO2 at room temperature (RT) (24ºC). Notably, the CeO2@rGO-based sensor upholds a significantly high response of 52.84 % towards 70 ppm of NO2, with an ultrafast response and recovery time of 7 s and 58 s respectively, with the LOD of 1 ppm. In addition, the CeO2@rGO flexible gas sensor exhibited long-term stability up to 30 days, solid repeatability, and stability in high relative humidity (RH) conditions. The marvelous sensing characteristics of the CeO2@rGO were attributed to the synergetic effect between CeO2 and rGO. The mechanism of sensing response was exhaustively interpreted by the "surface electron depletion layer mechanism". Certainly, the scientific investigation conducted in the present study will undeniably advance the possible uses of detecting NO2 at RT. © 2023 Elsevier B.V.

Π-d conjugated conductive coordination polymers (CCP) are an emerging class of materials that constitutes MOFs unique properties such as porosity and stability with electrical charge transport properties. The structural diversity and tunability of MOFs allow its application in electronics and selective gas sensing. This report deals with a reliable synthesis of room temperature (28 °C) conductive π-d conjugated metal-organic framework composed of Zn metal node and 3,6,7,10,11-hexahydroxytriphenylene (HHTP) organic ligand and its application in chemiresistive and Chem-FET sensing modality. The nature of as-synthesized MOF multiparametrically tested by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Uv-visible spectroscopy, energy dispersive spectroscopy (EDS), atomic force microscopy (AFM), Field emission scanning electron microscopy (FE-SEM), BET surface area analyzer, and current-voltage (I-V) characteristics for its structural, spectroscopic, elemental, morphological, surface and electrical properties respectively. Zinc-hexahydroxytriphenylene (Zn-HHTP) sensor was prepared on interdigitated electrodes on Si/SiO2 substrate, which was fabricated by photolithography process and tested for both chemiresistive and Chem-FET sensing modalities. Zn-HHTP sensor showed the highest selectivity, excellent sensitivity, stability, and fastest response among all reported carbon monoxide sensors in both modalities. Multivariate analysis was carried out using principal component analysis (PCA) which reveals high discriminating capability of Zn-HHTP sensor towards NH3, SO2 and CO. © 2023 Elsevier B.V.

An ultrafast and highly sensitive carbon monoxide gas sensor based on PEDOT/GO nanocomposites has been addressed in this work. A new approach was utilized to materialize PEDOT/GO via a straightforward and inexpensive polymerization in the presence of GO. Many characterization techniques, including FE-SEM, AFM, TGA, XRD, FTIR, Raman spectroscopy, and UV–Vis spectroscopy, have been utilized to confirm the successful formation of the PEDOT/GO nanocomposite. Moreover, the chemosensitivity modality has been used to measure the materials’ resistivity and sensing performance. The PEDOT/GO-based sensor exhibits excellent sensitivity when exposed to a wide range of CO concentrations, from 20 ppm to 270 ppm. Our experimental outcomes demonstrated that incorporating PEDOT into GO enhanced the sensor sensitivity (from 16% for pure PEDOT to 44% for composite), which resulted in quick response/recovery times (43 s/42 s) and exceptional long-term stability at room temperature. Based on the results of this work, it seems likely that the proposed sensor, with its low cost, simple development process, and excellent sensing performance, could be a good candidate for real-time CO detection. © 2022

Monitoring heavy metal ions (HMIs) in water is always a challenging and vital issue due to their hazardous effects on the environment and human health. Therefore, it is necessary to detect heavy metals in the water. Herein, we first-time report the use of silver nanoparticles (Ag NPs) incorporated copper benzene carboxylate (MOF-199) metal organic framework ( [email protected] ) for detection of heavy metal ions in water. A glassy carbon electrode-modified [email protected] electrochemical sensor probe was fabricated and showed a selective and sensitive response towards nickel (Ni(II)) ions only by cyclic voltammetry . The [email protected] sensor did not offer any cyclic voltammetric sensing response towards cadmium (Cd(II)), lead (Pb(III)), chromium (Cr(III)), and ferric (Fe(III)) ions (1 μM/L) at pH values ranging from 3 to 10. The [email protected] sensor displayed high sensitivity of 1.48 μA/nM on the exponential scale for Ni(II) ions at pH 7 and a lower detection limit of 6.06 nM/L with good reproducibility below US EPA suggested maximum contamination limit. The synthesized [email protected] was characterized by spectroscopic (viz. UV–visible spectroscopy, Raman spectroscopy and mapping, energy dispersive spectroscopy (EDS), Fourier transform infrared (FTIR) spectroscopy), surface area (viz. Brunauer–Emmett-Teller surface area analysis), electrochemical activity (viz. cyclic voltammetry, electrochemical impedance spectroscopy), morphological (viz. field emission scanning electron microscopy (FE-SEM)), structural (viz. X-ray diffraction (XRD)), and thermogravimetric analysis.

Heavy metal ions (HMIs) pollutants pose remarkable hazards to humans and the environment. Their toxicity is a concern for both aquatic life and humans. HMIs directly threaten humans when consumed through drinking water or aquatic species such as fish. Therefore, detecting, quantifying, and removing these pollutants from water sources is necessary. In this study, we fabricated a highly selective and sensitive Hg2+ ion electrochemical sensor using a solvothermally synthesized composite of silver nanoparticles (Ag NPs) and zinc benzene dicarboxylate (ZnBDC) (Ag@ZnBDC) metal–organic framework (MOF) at trace levels. The synthesized Ag@ZnBDC MOFs composite was studied using various characterization techniques: structural, spectroscopic, thermal, Brunauer-Emmett-Teller surface area, morphological, elemental, and electrochemical techniques. The electrochemical sensor was fabricated by drop-casting the Ag@ZnBDC composite onto a glassy carbon electrode, and its sensing properties were evaluated using cyclic voltammetry and differential pulse voltammetry techniques. Remarkably, the sensor exclusively and highly selectively responded to Hg2+ ions among Cd2+, Cr3+, Cu2+, Fe3+, and Pb2+ ions at a concentration of 1 μM. The Ag@ZnBDC sensor showed a limit of detection of 4.16 nM in the linear response within the concentration range of 1–10 nM for Hg2+ ions. © 2024 Elsevier Ltd
