摘要：
An ultrasensitive and selective electrochemical sensor has been constructed for the quantitative assay of dopa-mine (DA) based on hollow tubular manganese-cobalt sulfide (MnS/Co3S4) hybrids embedded on electrochem-ically reduced graphene oxide (ErGO). The MnS/Co3S4 heterostructures were created by two-step ion exchange method, of which Co9S8 with hollow tubular structures was fabricated by solvothermal method using the self-made cobalt chloride carbonate hydroxide (CO(CO3)0.35Cl0.20(OH)1.10) as precursor and sodium disulfide mon-ohydrate as sulfur source and manganese chloride as manganese sou...
