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 mu M, 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.
