Embodiment Construction

[0031] 1. Preparation method of Ni-MOF ultrathin nanobelts.

[0032] (1) Weigh glutaric acid (C 5 h 8 o 4 ) 3mmol, and 4mmol of NaOH, KOH or urea were dissolved in 10mL of a mixed solution of ethanol and water (the volume ratio of which was 1:1).

[0033] (2) Weigh nickel nitrate (Ni(NO 3 ) 2 •6H 2 O) 2mmol was added to 20mL of a mixed solution of ethanol and water (the volume ratio of which was 1:1), and a green and clear solution was obtained by a magnetic stirrer.

[0034] (3) Add the solution in step (1) into the mixed solution in step (2) while stirring, and stir with a magnetic stirrer for 20-30 minutes to obtain a mixed solution.

[0035] (4) Transfer the mixed solution obtained in step (3) to a 50mL polytetrafluoroethylene stainless steel reactor, and conduct a hydrothermal reaction at 180°C for 24 hours. Dry naturally at room temperature to obtain Ni-MOF ultrathin nanobelts.

[0036] (5) Verify the Ni-MOF ultrathin nanoribbons obtained in step (4):

Abstract

The invention discloses a Ni-MOF ultrathin nano belt, and a synthesis method and applications thereof, and belongs to the technical field of electrochemical sensing electrode material preparation. Glutaric acid (C5H8O4) and a soluble alkali are dissolved in an ethanol water solution to carry out neutralization reactions. Divalent nickel is dissolved in an ethanol water solution to prepare an ethanol solution of divalent nickel. The solution obtained through neutralization reactions and the ethanol solution of divalent nickel carry out hydrothermal reactions to prepare the Ni-MOF ultrathin nano belt, which has an excellent electrochemical responding property and ideal electrochemical stability and can be applied to electrochemical sensing.

Description

technical field [0001] The invention belongs to the technical field of preparation of electrochemical sensing electrode materials. Background technique [0002] Diabetes is a worldwide chronic disease characterized by hyperglycemia. Therefore, the detection of blood glucose level has increasingly become an important way for timely diagnosis and strict management of diabetes. Among the existing methods, the electrochemical detection method has increasingly attracted researchers' attention to the development of new glucose sensors due to its low cost, convenient operation, high sensitivity and strong selectivity. In the electrochemical detection method, the glucose enzyme sensor has high sensitivity and selectivity, but the enzyme is usually easily affected by stability and bound by high price, in which pH value, temperature, humidity and toxic chemicals will affect its stability. make an impact. To address these shortcomings, enzyme-free glucose sensors that can directly c...
