Bisphenol A is a pollutant issued from the degradation of plastics such as polycarbonate and epoxy resins, yet actual bisphenol A monitoring in environmental samples is limited. Here we present the electrochemical detection of bisphenol A with a novel composite, MoS₂–CoS₂/reduced graphene oxide, obtained by a facile two-step hydrothermal process using MoS₂ nanoflowers, CoS₂ nano-polyhedrons and reduced graphene oxide. Results show that the linear range of the electrochemical sensor is wider, of 0.02–200 μM, and the detection limit is lower, of 2.5 nM, than actual electrochemical sensors. These findings are explained by good conductivity and the presence of abundant active sites.

双酚 A 是聚碳酸酯和环氧树脂等塑料降解产生的污染物，但对环境样品中双酚 A 的实际监测是有限的。_{在这里，我们展示了使用新型复合材料 MoS 2} –CoS ₂ /还原氧化石墨烯对双酚 A 的电化学检测，该复合材料是通过使用 MoS ₂纳米花、CoS ₂纳米多面体和还原氧化石墨烯的简单两步水热法获得的。结果表明，与实际电化学传感器相比，电化学传感器的线性范围更宽，为0.02-200 μM，检测限更低，为2.5 nM。这些发现可以通过良好的导电性和丰富的活性位点的存在来解释。
