▎ 摘　　要

NOVELTY - High stain-resistant MXene-electrochemical reduced holey graphene (ERHG) electrochemical sensor is formed by compounding MXene and ERHG. USE - High stain resistance MXene-ERHG electrochemical sensor used as anti-pollution substrate to enhance and stabilize electrochemical signal. ADVANTAGE - The high stain-resistant MXene-ERHG electrochemical sensor has good linear range and low detection limit, and obvious anti-pollution effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing MXene-ERHG electrochemical sensor with high anti-pollution performance, which involves: a. mixing MXene solution with HGO solution and performing ultrasonic treatment to obtain MXene-HGO solution; b. dripping MXene-HGO solution on glassy carbon electrodes (GCE), and drying to obtain MXene-HGO/GCE; and c. placing MXene-HGO/GCE in phosphate-buffered saline (PBS) solution, and carrying out electrochemical reduction to obtain MXene-ERHG/GCE, namely target product.
