In this study, popcorn‐derived microporous carbon (PPC) was prepared by pyrolysis method under KOH activation, which was used as an electrochemical sensor material for simultaneous detection of hydroquinone (HQ), catechol (CC), and nitrite (NT). The prepared PPC/GCE exhibited highly electrocatalytic activity to the oxidation of HQ, CC and nitrite. The oxidation peaks for HQ (111 mV), CC (216 mV), and NT (854 mV) were well separated under the optimized conditions. The PPC/GCE showed a wide linear range of 3.0–700 μM, 3.0–500 μM and 5.0–10000 μM for HQ, CC and NT with detection limits of 1.45 μM, 0.49 μM and 1.5 μM, respectively. The KOH‐activated PPC is a promising electrode material for fabricating selective and sensitive electrochemical sensors.

A simple and highly selective electrochemical sensor based on carbonized lotus stem (CLS) was developed for the simultaneous determination of hydroquinone (HQ), catechol (CC), and nitrite (NT) by using cyclic voltammetry (CV) and amperometry (AMP) methods. The CLS was characterized by the methods including field emission scanning electron microscopy (FE‐SEM), Raman spectrum, FT‐IR spectrum and X‐ray diffraction (XRD). Brunauer‐Emmett‐Teller (BET) method was used to evaluate the pore structure and surface area of CLS. The oxidation peaks for HQ (116.2 mV), CC (220.1 mV), and NT (818.9 mV) were well separated under optimized conditions, which improved their simultaneous determination. The CLS modified electrode showed a good linear range between 1.0×10 −6 to 7.0×10 −4 M for HQ, and the detection limit was calculated as 0.15 μM. For CC the linear relationship was 1.0×10 −6 to 3.0×10 −3 M with the detection limit of 0.11 μM. For NT the linear relationship was 5.0×10 −7 to 4.0×10 −3 M with the detection limit of 0.09 μM. The results indicated that the intrinsic structure of natural biomass can be expected to design porous carbon for electrochemical sensors.

“…Detecting phenolic compounds, including HQ and RS, presents challenges in analytical chemistry. Various approaches have been explored, such as high-performance liquid chromatography (HPLC), 4 spectrophotometry, 5 fluorescence, 6 chemiluminescence, 7 capillary electrochromatography, 8 gas chromatography/mass spectrometry, 9 and electroanalytical methods, among others. Despite their utility, these techniques are often marred by complexities in sample preparation, time-intensive procedures, and high costs.…”
