Bisphenol A (BPA) is a worldwide used endocrine disrupting chem. that can migration from food containers and packaging, resulting in bioaccumulation of BPA in humans and causing adverse health effects. Porous electrodes have been proved with large surface areas and high sensing abilities in electrochem. detection of BPA. However, how to tailor the pore sizes to further improve the sensing performance is still a great challenge. Here, we delicately tailored the diameters of carbon nanofibers (CNFs) by adjusting electrospinning parameters to have optimal mesopore structure for strong adsorption of hemin that has been demonstrated with high electrocatalytic activity for BPA sensing. Benefiting from the optimal mesopores structure of CNFs and the synergistic effect of hemin and CNFs, this hemin@CNFs based sensor achieves an ultrahigh sensitivity of 40.97μA cm-2μM-1, a low detection limit of 3.1 nM and satisfactory recoveries from 90.2% to 104.2% in the direct detection of BPA in liquors. This work offers a promising sensing platform for ultrasensitive monitoring of BPA. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8SDS of cas: 620-92-8).
4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.SDS of cas: 620-92-8
