Sandwich structure confined gold as highly sensitive and stable electrochemical non-enzymatic glucose sensor with low oxidation potential
文献摘要：
The preparation of highly sensitive and stable non-enzymatic glucose sensors is critical to the prevention and treatment of diabetes.Fe3O4@Au@CoFe-LDH is prepared through a spontaneous galvanic displace-ment reaction.A series of structural characterizations testify the successful formation of Fe3O4@Au@CoFe-LDH electrocatalyst,with the Au intercalating between Fe3O4 and LDH to form the sandwich structure.Cyclic voltammetry tests indicate that Au is responsible for the electrocatalytic oxidation of glucose.The characterizations of the electrochemical sensor for glucose detection indicate that Fe3O4@Au@CoFe-LDH possesses high sensitivity of 6342 μA mM-1 cm-2,with an extremely low oxidation potential of 0.82 V vs.RHE.Even with the high glucose concentration of 15 mM,the sensitivity remains at 4359 μA mM-1 cm-2.Due to the broad linear detection range(0.0375 to 15.64 mM)and the low limit of detec-tion(12.7 μM),Fe3O4@Au@CoFe-LDH is applicable towards practical application.Thanks to the sandwich structure,which confines the Au in between Fe3O4 and CoFe-LDH,the Fe3O4@Au@CoFe-LDH glucose sen-sor shows high long-term stability and satisfactory selectivity.The successful synthesis of the sandwich-structured Fe3O4@Au@CoFe-LDH provides a new conception for the design of highly sensitive and stable non-enzymatic glucose electrodes.
