Fabrication of a ZnO Hexagonal Plates/rGO Composite for Application in Nitrite Sensing and Photocatalytic Hydrogen Production

“…of DL, and sensitivity of ZnO/rGO/GCE with previous reports [7][8][9][10][11][12][13][14][15]. S. No.…”

“…[3][4][5][6] Among toxic species, nitrite ion (NO 2 À ) is the most common inorganic contaminant, found in food, or waste/drinking water. [7] Thus, there is a great interest in the sensing and determination of NO 2 À for environmental safety, food security, and human health. [8][9][10] The presence of excessive NO 2 À may stimulate the irreversible-oxidation of hemoglobin.…”

“…[25] In the past years, various nanostructured semiconducting metal-oxides and their hybrid composites have been widely explored for the development of NO 2 À sensor. [7][8][9][10][11][12][13][14] In this association, zinc oxide (ZnO) has attracted scientific researchers due to its cost-effectiveness, good electron mobility, electrocatalytic property, and decent surface area. [27] ZnO has been extensively used in the development of various sensors and biosensors.…”

Bowl‐shaped hollow N‐doped carbon as an electrochemical platform for the highly selective and sensitive electrochemical detection of isoprenaline in pharmaceutical injection

“…The deconvolution spectrum of N1s is shown in Figure 2e, with deconvolution peaks observed at 405.55, 401.21, 400.44, and 398.48 eV, for Oxidated N, Graphitic N, Pyrrolic N, and Pyridinic N, respectively [30]. The deconvolution spectrum of N1s is shown in Figure 2e, with deconvolution peaks observed at 533.38 and 532.33 eV, for CÀ O and C=O, respectively [31]. The Raman spectra are shown in Figure S1.…”

Selective determination of nitrite in water and food samples using zirconium oxide (ZrO2)@MWCNTs modified screen printed electrode

“…Both techniques are used because of their high fast response, and rapid analysis. 23,24 For better electrochemical performance, modifications of working electrode surfaces with sensing nanomaterials can be applied while using disposable screen-printed electrodes, which have extra advantages of preventing contamination by sample impurities, and less sample volume is needed for analysis. 25,26…”
