“…High-purity graphite powder with a particle size of 1 to 10 micrometers fabricates electrodes [150]. Further, the graphite powder's purity greatly influences the electrodes' electrochemical performance [151]. In addition, the organic binder helps the modifier (MOF) bind at the electrode surface, which must be stable, insoluble, and impurities-free.…”

Metal-organic frameworks (MOF) are a class of porous hybrid materials of metal ions linked by organic bridging ligands. These materials consist of different families of crystalline frameworks with metal ions and metal-ion clusters linked by the coordination bonds with suitable organic ligands. These porous materials possess high surface area, variable pore sizes, various functions, and excellent thermal stability. As a result, these unique and tailored MOF materials found varied applications in electrochemical sensor development. The review critically examines the approach to synthesizing a wide range of MOF compounds. The utilization of MOF in fabricating a small-scale sensor device demonstrates the ability to detect various water contaminants in aquatic environments. Moreover, it showcased an in-depth advancement in sensor and device development utilizing MOFs materials. The efficient use of electrochemical sensors is discussed critically and presents these studies’ challenges and future perspectives.

“…Also, some researches focus on encapsulation of metal salen complex in the zeolitic host for electro-catalytic oxidation of methanol [ 54 – 57 ]. Solid-state electrochemical sensors have received more interest because they make it possible to consider the analyte in the real time [ 58 ]. Therefore, several features can be modified through a sensor design to increase the selectivity and sensitivity, such as the size and shape.…”

Goal of current study was fabrication of novel voltammetric nanosensor for the synchronize quantification of ascorbic acid (AA) and paracetamol (PAR) by nickel-cobalt salen complexes encapsulated in the supercages of NaA nanozeolite modified carbon paste electrode (NiCoSalenA/CPE). For this purpose, NiCoSalenA nanocomposite was firstly prepared and characterized by various methods. Also, cyclic voltammetry (CV), choronoamperometry (CHA) and differential pulse voltammetry (DPV) were utilized to evaluate performance of the modified electrodes. The effects of pH and modifier amount were considered on the electrochemical oxidation of AA and PAR on the surface of NiCoSalenA/CPE. Results from this method indicated that pH of 3.0 in phosphate buffer solution (0.1 M) and 15 wt% of NiCoSalenA nanocomposite in the modified CPE results in the maximum current density. The oxidation signals of AA and PAR was amplified affectively at NiCoSalenA/CPE versus unmodified CPE. The limit of detection (LOD) and linear dynamic range (LDR) for the simultaneous measurement of them were founds to be 0.82 and 2.73–80.70 for AA and 0.51 µM, 1.71–32.50 and 32.50–137.60 µM for PAR, respectively. The catalytic rate constants ( k cat ) were attained to be 3.73 × 10 7 and 1.27 × 10 7 cm 3 mol −1 s −1 for AA and PAR via CHA method, respectively. Also, the amounts of diffusion coefficient ( D ) were found to be 1.12 × 10 −7 and 1.92 × 10 −7 cm 2 s −1 for AA and PAR, respectively. The average value of electron transfer rate constant between NiCoSalenA/CPE and PAR was obtained to be 0.016 s −1 . The NiCoSalen-A/CPE displayed worthy stability, repeatability and extraordinary recovery for simultaneous measurements of AA and PAR. Application of offered sensor was confirmed by quantifying concentrations of AA and PAR in human serum solution as a real sample.
