An electrochemical sensor based on marine biomass shrimp shell-derived porous carbon (SSPC) modified glassy carbon electrode (GCE) was developed for the detection of hydroquinone (HQ) in this paper. The resultant SSPC was characterized by different methods including scanning electron microscopy and Fourier transform infrared spectroscopy. Brunauer-Emmett-Teller method was used to evaluate the pore structure and surface area of SSPC. The electrochemical behaviors of SSPC/GCE were explored by cyclic voltammetry and differential pulse voltammetry. The SSPC/GCE demonstrated linear response ranges of 5.0–25.0 μM and 25.0–1200.0 μM for HQ analysis with the limit of detection as 0.18 μM (S/N = 3). Additionally, the method had been successfully applied to determine HQ in real lake water sample, which provided potential applications in further sensing study.

Three-dimensional graphene (3DG) is presented as an excellent electrocatalyst for the simultaneous detection of hydroquinone (HQ) and catechol (CC) by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Morphology and structure of 3DG were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). Compared with the bare glassy carbon electrode (GCE), the 3DG-modified GCE exhibits better electrocatalytic activity in the redox reaction of HQ and CC. The 3DG-modified GCE detects both isomers selectively and sensitively by DPV and CV, latter showing a peak-to-peak separation of 190 mV. The detection limits for HQ and CC can reach 0.35 and 0.6 μM (S/N = 3), respectively, with wide linear ranges of 1-1000 μM in the presence of 50 μM of the respective other isomer. This work provides a strategy for the development of high-performance electrochemical sensors.

A biomass-derived porous carbon (CSC–PA–800) was synthesized from discarded coconut shells through a green and sustainable KOH activation route combined with pre-carbonization and high-temperature carbonization. This work introduces a novel eco-friendly electrochemical sensing platform that integrates biomass valorization with high-performance detection of hydroquinone (HQ) and catechol (CC), two representative phenolic pollutants. Benefiting from its hierarchical porous framework and superior conductivity, CSC–PA–800 effectively facilitates analyte adsorption and electron transfer. Under optimized electrochemical conditions, the CSC–PA–800/glassy carbon electrode (GCE) sensor achieves a wide linear range (1–700 μM) and low detection limits (0.33 μM for HQ and 0.29 μM for CC) in 0.1 mol L⁻¹ PBS (pH 7.0), along with excellent repeatability (RSD < 1%), high selectivity and robust stability even in complex matrices. Furthermore, direct validation against the standard high-performance liquid chromatography (HPLC) method confirms its analytical accuracy, with recoveries of 95.38–104.64% in real tap and river water samples. These results underscore the unique contribution of this work in developing a low-cost, sustainable and high-sensitivity sensing platform, offering a scalable strategy for green analytical applications and real-world environmental monitoring.

In this paper, a glassy carbon electrode (GCE) modified with TiO 2 -ZnO-reduced graphene oxide (TiO 2 -ZnO-rGO) nanocomposites was designed for the selective and simultaneous quantification of hydroquinone (HQ) and catechol (CA). The TiO 2 -ZnO-rGO nanocomposites were prepared by a simple ultraviolet irradiation method for the first time. In the process of ultraviolet radiation, the photogenerated electrons in TiO 2 and ZnO were transfered into GO which was then reduced to form rGO. Benefiting from functional properties of different components and synergistic effect, the TiO 2 -ZnO-rGO nanocomposites exhibited excellent sensing performance for the selective and simultaneous determination of HQ and CA. Under the optimized conditions, the linear ranges for selective assay of HQ or CA in the existence of 40 µM of the respective isomer are 5–500 µM. The linear ranges for simultaneous assay of HQ and CA are obtained from 0.1 to 100 µM with the detection limits of 0.03 µM (HQ) and 0.05 µM (CA), respectively. The TiO 2 -ZnO-rGO/GCE also displayed excellent stability and satisfactory recovery when applied for real water samples analysis.

We have synthesized a virtually monodisperse gold-graphene (Au-G) nanocomposite by a single-step chemical reduction method in aqueous dimethylformamide solution. The nanoparticles are homogenously distributed over graphene nanosheets. A glassy carbon electrode was modified with this nanocomposite and displayed high electrocatalytic activity and extraordinary electronic transport properties due to its large surface area. It enabled the simultaneous determination of hydroquinone (HQ) and catechol (CC) in acetate buffer solution of pH 4.5. Two pairs of well-defined, quasi-reversible redox peaks are obtained, one for HQ and its oxidized form, with a 43 mV separation of peak potentials (ΔE p ), the other for CC and its oxidized form, with a ΔE p of 39 mV. Due to the large separation of oxidation peak potentials (102 mV), the concentrations of HQ and CC can be easily determined simultaneously. The oxidation peak currents for both HQ and CC increase linearly with the respective concentrations in the 1.0 μM to 0.1 mM concentration range, with the detection limits of 0.2 and 0.15 μM (S/N = 3), respectively. The modified electrode was successfully applied to the simultaneous determination of HQ and CC in spiked tap water, demonstrating that the Au-G nanocomposite may act as a high-performance sensing material in the selective detection of some environmental pollutants.
Au-graphene (Au-G) nanocomposites were synthesized through a single-step chemical reduction method. Nearly monodispersed Au nanoparticles were uniformly distributed over the 2D graphene nanosheets without aggregation. The glassy carbon electrode modified with Au-G nanocomposites, Au-G/GCE, shows high resolution capability in simultaneous determination of hydroquinone (HQ) and catechol (CC) in acetate buffer solutions (HAc-NaAc, pH 4.5).

Hydroquinone (HQ), a toxic and persistent pollutant, requires sensitive and reliable detection strategies beyond conventional chromatographic or electrochemical methods. Here, we report a nitrogen-doped 1T/2H-MoS 2 /Co 9 S 8 /CdS ternary nanozyme synthesized via a urea-mediated hydrothermal route. Urea acts as a bifunctional agent, simultaneously stabilizing the metastable 1T-MoS 2 phase and introducing sulfur vacancies through nitrogen substitution. This defect-phase engineering optimizes the electronic structure, as evidenced by a 0.2 eV positive shift in Mo 3d binding energy, and exposes coordinatively unsaturated Mo sites that accelerate hydroxyl radical (•OH) generation. Coupled with the redox activity of Co 9 S 8 and the adsorption capability of CdS, the composite exhibits markedly enhanced peroxidase-like activity, characterized by higher catalytic turnover and stronger H 2 O 2 affinity compared to undoped systems. A colorimetric sensor constructed from this platform enabled ultrasensitive HQ detection with a detection limit of 0.29 μM and excellent recoveries (100.18% to 101.64%) in spiked real water samples, while maintaining strong selectivity and operational stability. This work establishes a nitrogen-doping-driven paradigm for phase stabilization and defect regulation, offering a generalizable strategy for designing high-performance nanozymes for environmental monitoring.

In this work, Ni-Zn-doped porous carbon materials (Ni@C) with regular dodecahedral morphologies were synthesized by calcination of Ni-doped ZIF-8 as a template, and applied in electrochemical sensing and quantitative electrochemical sensors to detect Hydroquinone (HQ), The uniformly dispersed Ni in Ni@C serves as the catalytically active material, and the synergistic effect of elemental Zn and porous carbon improves the electron transport efficiency of the material. The developed Ni@C electrochemical sensor detected HQ alone with a sensitivity of 180 μA μM -1 cm -2 and a linear range of 9.1 nM-80 μM. The results demonstrate that the enzyme-free electrochemical sensor based on Ni@C/GCE exhibits good sensitivity, a wide linear range and excellent selectivity. At the same time, the problem of the general conductivity of metal-organic framework (MOF) materials is solved, which provides a new idea for the application of such new materials in the direction of electrochemistry.

In this work, Cu/N-C derived from MOF composites were synthesized and characterized by SEM, XRD, FTIR, XPS and EIS, which was modified on the glassy carbon electrode (GCE) to construct a novel electrochemical sensor (Cu/N-C/GCE). Due to the good electrical conductivity and abundant catalytic active sites of Cu/N-C, Cu/N-C/GCE exhibited excellent electrocatalytic performance for catechol (CC) and hydroquinone (HQ) with the oxidation peak potential difference of 112 mV. The proposed sensor could realize the simultaneous detection of CC and HQ successfully. Under optimal conditions, the redox peak currents of both CC and HQ have good linear relationship with their concentrations in the ranges of 0.50–100.00 μM and 0.50–150.00 μM with the detection limits for CC and HQ of 0.12 μM and 0.09 μM, respectively. At the same time, the sensor exhibits good stability, reproducibility and selectivity in the analysis of practical samples.

All-organic aqueous batteries are deemed attractive energy storage systems for some application scenarios demanding recyclability or wearability. The efficient redox activity of quinone/hydroquinone-derived couples in biosystems inspires us to develop advanced batteries based on them. However, designing such an all-organic aqueous battery is challenging in selecting suitable electrolytes and active materials. A possible battery configuration consisting of the 9, 10-anthraquinone (AQ) anode, hydroquinone derivatives cathode, and weak acid metal-ion aqueous electrolyte is demonstrated herein. The molecular configuration of quinones and ionic type of electrolytes affect the redox behaviors of electrodes. Gratifyingly, a combination of AQ-tetrachlorohydroquinone-Al 2 (SO 4 ) 3 exhibits optimal performance. The underlying work mechanism of this full-battery configuration is disclosed by electrochemical and structural characterizations, finding that H + and Al 3+ are jointly involved in the redox reaction of quinone electrodes, and Al 3+ plays a crucial role. This work inaugurates a new framework for designing an all-organic aqueous battery.

A quinone/hydroquinone redox loop drives metal-free photocatalytic self-Fenton reactions. • Semiquinone radicals on THQ carbonyl sites activate H 2 O 2 into •OH radicals. • Accelerates CIP degradation by 4.98-fold and mineralizes distillery wastewater. Photocatalytic self-Fenton catalysts synergistically remove organic pollutants by coupling photosynthesis of H 2 O 2 with the Fenton reaction. However, metal-based self-Fenton systems inevitably generate secondary pollution associated with transition metal sludge disposal. Here, we rationally designed a metal-free graphitic carbon nitride (g-C 3 N 4 ) catalyst covalently grafted with tetrahydroxy-1,4-benzoquinone (THQ) to construct an efficient, sustainable photocatalytic self-Fenton system. The integrated THQ not only enhances the visible-light harvesting and directional separation of photogenerated carriers of g-C 3 N 4 , but also serves as a dual-functional active center. Specifically, THQ is proposed to facilitate the two-electron oxygen reduction reaction (2e - ORR) for in-situ H 2 O 2 generation and subsequently promote the activation of the generated H 2 O 2 into highly reactive hydroxyl radicals (•OH) through its quinone/hydroquinone (Q/QH 2 ) redox cycle. Consequently, the THQ/g-C 3 N 4 composite exhibits exceptional catalytic performance, achieving a 4.98-fold enhancement in the degradation rate constant of ciprofloxacin (CIP) within 2 h compared to pristine g-C 3 N 4 . Furthermore, the catalyst demonstrates remarkable practical applicability, achieving a 50 % total organic carbon (TOC) removal efficiency in Chinese Baijiu distillery wastewater within 5 h. This study establishes metal-free, photocatalytic self-Fenton catalysis as a promising strategy for sustainable environmental remediation.

Abstract It is needed to speed up the development of a sensitive detection platform for simultaneous determination of dihydroxybenzene isomers with harmful properties. Here, two isomorphic Metal–organic frameworks (MOFs) [Zn(Trz)(R-BDC) 1/2 ] (FJU-40-R, R = H or NH 2 ; Trz = 1,2,4-Triazole; H-BDC = terephthalic acid) were selected to derive two N-doping porous carbon (NPC) materials. Further, a strategy for constructing electrochemical sensors for simultaneous determination of hydroquinone (HQ) and catechol (CT) was proposed by the MOF-derived NPC modifying glass carbon electrode (GCE). It was found that HQ and CT had good responses on NPC-FJU-40-H/GCE, but had no obvious responses on NPC-FJU-40-NH 2 /GCE. NPC-FJU-40-H/GCE displayed excellent reproducibility, stability, and anti-interference. Under the optimal conditions, the linear ranges of HQ and CT on NPC-FJU-40-H/GCE were 1 ~ 70 µmol L −1 and 1 ~ 100 µmol L −1 with the detection limits of 0.18 µmol L −1 for HQ and 0.31 µmol L −1 for CT, respectively. Although the porous carbon (PC) derived from MOFs has been applied in electrochemical sensing, the effect of the ligand functional groups of isomorphic MOFs on the electrochemical properties of the derived PC materials is still lack of relevant research. Our research provided an idea that the electrocatalysis properties of MOF-derived porous carbon materials could be tuned by changing the functional groups in ligands of isomorphic MOFs in electrochemical sensing field. Graphical abstract A feasible strategy was proposed by changing the ligands of the two isomorphic MOFs (FJU-40-H and FJU-40-NH 2 ) to tune the electrocatalysis properties of MOF-derived N-doped porous carbon materials for the simultaneous determination of dihydroxybenzene isomer.

A novel additive system comprising bis-(sodium sulfopropyl)-disulfide, polyethylene glycol and hydroquinone (HQ) was developed and investigated to achieve high rate copper electrodeposition at high temperature. HQ, as the key additive compound in this system, refines the Cu grain, makes the coating surface bright and smooth at high current density. The underlying mechanism of the additive-assisted electroplating was investigated through electrochemical, morphological characterizations and molecular dynamics simulation. Nanocubical copper particles were found through chronoamperometry tests, which explains the fine crystalline Cu grains and the bright coating surface. Additionally, the formation of the nanocubical copper particles is caused by the different adsorption energies of HQ on (311), (111) and (220) crystal faces and further leads to a strong suppression on the (220) orient crystal faces. Moreover, the electroplating results of through-holes illustrate the feasibility of this additive system in practical applications.
