Non-enzymatic Glucose Sensor Based on Porous Foam Au/MXene Nanocomposites
文献摘要：
A novel electrochemical non-enzymatic glu-cose sensor based on three-dimensional Au/MXene nanocomposites was developed.MXenes were prepared using the mild etched method,and the porous foam of Au nanopar-ticles was combined with the MXene by means of in situ synthesis.By controlling the mass of MXene in the synthesis pro-cess,porous foam with Au nanoparticles was obtained.The three-dimensional foam structure of nanoparticles was confirmed by scanning electron microscopy.Cyclic voltammetry and electrochemical impedance spectroscopy were used to study the electrochemical performance of the Au/MXene nanocomposites.The Au/MXene nanocomposites acted as a fast redox probe for non-enzymatic glucose oxidation and showed good performance,including a high sensitivity of 22.45 μA·(mmol/L)-1.cm-1 and a wide linear range of 1-12 mmol/L.Studies have shown that MXene as a catalyst-supported material is beneficial to enhance the conductivity of elec-trons and increase the loading rate of the catalyst materials.The foam structure with Au nanoparticles can provide a larger surface area,increase the contact area with the molecule in the catalytic reaction,and enhance the electrochemical reaction signal.In summary,this study shows that Au/MXene nanoparticles have the potential to be used in non-enzymatic glucose sensors.
