摘要：
A gold nanoparticles decorated the seedling of white myoga ginger-derived biochar (WBC/Au) was prepared and characterized. The WBC/Au nanocomposites exhibited highly porous structure, good dispersibility in water, and high specific surface area. Further, the nanocomposite prepared at 850 degrees C (WBC/Au-850) was used as the electrode materials for simultaneous determination of hydroquinone and catechol. Under the optimized conditions, the WBC/Au-850-15 nanocomposite modified electrode exhibited very high sensitivities and very low detection limits for simultaneous determination of hydroquinone and catechol. Moreover, this sensor was further used to detect hydroquinone and catechol in tap water sample with satisfactory results.
