Zinc oxide nanoparticles（ZnO NPs） and two⁃dimensional layered titanium carbide（Ti3C2T x ） were synthesized via hydrothermal method and liquid phase chemical etching，respectively.Titanium carbide/zinc oxide（Ti3C2T x /ZnO） composites with varying mass ratios were prepared using electrostatic self⁃assembly technology.Gas⁃sensitive sensing films were fabricated through screen printing and their gas sensitive properties were studied.The composite structure was characterized by X-ray powder diffraction（XRD） and scanning electron microscopy（SEM）.The results showed that ZnO NPs were uniformly distributed on the surface of Ti3C2T x with a two⁃dimensional accordion shape and interspersed between layers.In the detection of five typical VOCs gases including ethanol，acetone，methanol，formaldehyde，and toluene，the composite exhibited excellent sensing performance towards ethanol gas.At an optimal operating temperature of 250 ℃，M/ZNPS1（with a Ti3C2T x mass fraction of 6.25%） displayed a sensitivity（Ra/Rg=11.27） to ethanol at a volume fraction of 0.01%，which was 8.8 times higher than that of pure Ti3C2T x alone（Ra/Rg=1.28）.Furthermore，it demonstrated exceptional response/recovery time characteristics（4 s/8 s），as well as remarkable selectivity and long⁃term stability.The gas⁃sensitive mechanism of Ti3C2T x /ZnO composites was discussed from the point of view of carrier transport between electrodes，which had a potential application prospect for low concentration ethanol gas.
