“…The theoretical bandgap energies (BGE) of the obtained HgO NPs and HgO.CNT NCs were calculated using the equation ( 1) and found to be 5.49 and 5.54 eV, respectively. Following that, hv vs (αhv) 2 were plotted and then extended to the x-axis by using the Tauc's equations (2)(3)(4). The natural BGE for HgO NPs and HgO.CNT NCs were determined from the extended curves to be 2.8 and 3.6 eV, respectively (Figure 1b).…”

“…But in higher amount causes gastric discomfort. [3,4] The detection of ascorbic acid was previously described using standard methods such as chemiluminescence, capillary zone electrophoresis, optical and colorimetric detection, HPLC, enzyme fluorimetry, GC-MS, GC, and photo electrochemistry. These procedures are time-consuming, complicated, and costly, making them unsuitable for widespread organic acid detection.…”

In an alkaline solution, mercuric oxide decorated carbon nanotube nanocomposites (HgO.CNT NCs) were manufactured utilizing an uncomplicated wet-chemical approach. Ultra-Violet spectroscopy (UV-Visible), Fourier Transform Infra-red spectroscopy (FTIR), Powder X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), and Field Emission Scanning Emission Microscopy (FESEM), X-ray Electron Dispersive Spectroscopy (XEDS) techniques were applied to examine the HgO.CNT NCs that had been prepared. Ascorbic acid sensor was developed upon light coating of HgO.CNT NCs on polished Glassy carbon electrode (GCE) modified with nafion (Nf). Analytical performance of the selected ascorbic acid sensor was achieved such as sensitivity, Limit of quantification (LOQ), Limit of detection (LOD), Linear dynamic range (LDR), extended reliability, interference effect experimentation, and actual sample inspection using a consistent current-voltage approach. Calibration curve of the suggested sensor was observed to be linear (R 2 = 0.9957) throughout a broad range of ascorbic acid concentrations (100.0 pM ∼ 100.0 mM) at a voltage of 0.8 V. The calibration curve yielded analytical parameters such as sensitivity (632.91 pAμM À 1 cm À 2 ), LOQ (255.0 pM), LOD (76.50 pM), and LDR (100.0 pM ∼ 1.0 mM) for the proposed ascorbic acid sensor (GCE/HgO.CNT NCs/Nf). The wet-chemical synthesis of HgO.CNT NCs is a good development of nanocompositeoriented sensor advancement in medical sciences with nonenzymatic detection of biological substances. This proposed sensor applied to selective ascorbic acid detection in biological samples and obtained logical outcomes.

The electrochemical preparation of NaClO has been widely used for the production of industrial disinfectant. To reduce the cost of electrode preparation using the brushing method, this paper introduces a method for the electrodeposition for RuO2/Ti and RuO2‐IrO2/Ti preparation and NaCl solution electrolysis. The deposition of Ir improves the uniformity and stability of the RuO2/Ti electrode. The optimum preparation conditions and additive concentrations were investigated in detail through the orthogonal experiment. By adjusting the electroplating time, temperature and voltage, the electrode with a high content of available chlorine was synthesized successfully. The physicochemical properties of the as‐prepared RuO2/Ti and RuO2‐IrO2/Ti were determined by XRD, SEM‐EDS, and XPS, and the electrochemical performance and lifetime of the RuO2/Ti and RuO2‐IrO2/Ti was verified via an electrochemical workstation. Uniform and stable RuO2/TiO2 and RuO2‐IrO2/TiO2 were synthesized successfully for the electrolysis of the NaCl solution.

plays a vital role in biological metabolisms, for example, the digestion of amino acids, as well as the synthesis of adrenalin, certain hormones, and neurotransmitters. [2] AA has also been commonly used for the prevention and treatment of scurvy, [3] cancer, [4] common cold, [5] and AIDS, [6] etc. The design and implementation of cost-effective, high-performance electrochemical sensors for the rapid and accurate quantification of AA concentration in foods or biological fluids are important for many societally pervasive applications such as clinical diagnostics, [7] wearable health monitoring, [8] food safety, [9] and environmental monitoring. [10] However, the direct electrooxidation of AA on the surface of the bare electrodes is irreversible. [11] Moreover, the subsequent hydrolysis of the reaction will cause electrode fouling with large overpotential, poor selectivity, low sensitivity, and unsatisfactory reproducibility. [12] Nanostructured catalysts with large specific surfaces and abundant active sites appeal to highly sensitive electrochemical sensing of various chemicals. Various nanomaterials, such as conducting polymers, [13] carbon materials, [14] and metal oxides, [15] have been explored for modifying the electrodes to efficiently detect AA, Nanostructured piezoelectric semiconductors offer unprecedented opportunities for high-performance sensing in numerous catalytic processes of biomedical, pharmaceutical, and agricultural interests, leveraging piezocatalysis that enhances the catalytic efficiency with the strain-induced piezoelectric field. Here, a cost-efficient, high-performance piezo-electrocatalytic sensor for detecting l-ascorbic acid (AA), a critical chemical for many organisms, metabolic processes, and medical treatments, is designed and demonstrated. Zinc oxide (ZnO) nanorods and nanosheets are prepared to characterize and compare their efficacy for the piezo-electrocatalysis of AA. The electrocatalytic efficacy of AA is significantly boosted by the piezoelectric polarization induced in the nanostructured semiconducting ZnO catalysts. The charge transfer between the strained ZnO nanostructures and AA is elucidated to reveal the mechanism for the related piezo-electrocatalytic process. The lowtemperature synthesis of high-quality ZnO nanostructures allows low-cost, scalable production, and integration directly into wearable electrocatalytic sensors whose performance can be boosted by otherwise wasted mechanical energy from the working environment, for example, human-generated mechanical signals.
