Summary: Mxenes, a class of two-dimensional carbon-nitrogen compounds, were studied for the detection of paraquat (PQ) using an Ag-TiO2/MXene composite material. The detection limit reached 0.01 μM and the linear range was 0.05 to 15 μM. The composite material exhibited excellent anti-interference properties and its performance can be attributed to the synergistic effect of Ag and TiO2 on MXene.
