This review article compiled previous reports in the fabrication of hydroquinone (HQ) electrochemical sensors using differently modified electrodes. The electrode materials, which are also called electrocatalysts, play a crucial role in electrochemical detection of biomolecules and toxic substances. Metal oxides, MXenes, carbon-based materials such as reduced graphene oxide (rGO), carbon nanotubes (CNTs), layered double hydroxides (LDH), metal sulfides, and hybrid composites were extensively utilized in the fabrication of HQ sensors. The electrochemical performance, including limit of detection, linearity, sensitivity, selectivity, stability, reproducibility, repeatability, and recovery for real-time sensing of the HQ sensors have been discussed. The limitations, challenges, and future directions are also discussed in the conclusion section. It is believed that the present review article may benefit researchers who are involved in the development of HQ sensors and catalyst preparation for electrochemical sensing of other toxic substances.
这篇综述文章汇编了先前关于使用不同修饰电极制备对苯二酚（HQ）电化学传感器的报告。电极材料，也称为电催化剂，在生物分子和有毒物质的电化学检测中起着至关重要的作用。金属氧化物、MXenes、碳基材料（如还原氧化石墨烯（rGO）、碳纳米管（CNTs）、层状双氢氧化物（LDH））、金属硫化物和混合复合材料被广泛用于制备HQ传感器。文中讨论了HQ传感器实时传感的电化学性能，包括检测限、线性、灵敏度、选择性、稳定性、重现性、重复性和回收率。结论部分还讨论了局限性、挑战和未来方向。相信本综述文章可能会使参与HQ传感器开发以及用于其他有毒物质电化学传感的催化剂制备的研究人员受益。
