In-situ Growth of β-MnO2 Nanofibers as Transduction Layer of All-solid Ion Selective Electrode for Detection of Pb(Ⅱ)
A novel β-MnO2 NF/rGO nanomaterial with strong lipophilicity and large capacitance was syn-thesized by controlling β-manganese dioxide nanofibers in-situ growth on reduced graphene oxide.Mean-while,it is still unknown about how the transduction layer contributes to the ion selectivity coefficient. So,researchers used numerical simulations to construct a transduction layer-membrane-solution interface model coupled with the transduction layer,considering the membrane-transduction layer interface.Fur-thermore,the potential display is given,and the corresponding ion selectivity coefficient is calculated ac-cording to the simulation results.
