Abstract

The invention belongs to the field of electrochemistry, and particularly relates to an ultra-thin MXene nanometer material. A preparation method comprises the following steps of ultrasonically dispersing a plurality of layers of MXenes into dimethyl sulfoxide to form a stably dispersed turbid liquid, stirring, carrying out ultrasonic treatment, and carrying out centrifugal water washing to obtainthe ultra-thin MXene nanometer material. The application of the ultra-thin MXene nanometer material in detection of catechol is provided. A solution of catechol is added into an acetic acid-sodium acetate buffer solution, and a three-electrode system is adopted for detection with an electrode modified by the ultra-thin MXene nanometer material as a working electrode, an Ag / AgCl electrode as a reference electrode and a platinum electrode as an auxiliary electrode. The MXene has unique metal conductivity, biocompatibility and good dispersion in a water phase, and the ultra-thin MXene nanometer material can accelerate an electron transfer rate, so that the sensitivity and selectivity of an electrochemical sensor can be effectively improved.

Description

technical field

[0001] The invention belongs to the field of electrochemistry, and in particular relates to an ultrathin MXene nanometer material and its preparation method and application. Background technique

[0002] Catechol is a natural bisphenol compound commonly found in plants such as tea and fruit, as well as in wine, beer, fruit juice and some traditional Chinese medicines. Catechol has been extensively studied due to its biological importance as an antioxidant, antiviral and modulator of enzyme activity. In addition, the widespread discharge of catechols in industrial wastewater and exhaust gas may cause severe environmental pollution. Therefore, it is necessary to develop a highly sensitive, rapid and stable analytical method for the determination of catechol. In recent years, various analytical methods have been applied to the determination of catechol, especially spectrophotometry, gas chromatography and high performance liquid chromatography. However, these...
