Abstract

Benefiting from the excellent electrical conductivity and unique chemical properties, MXene-based sensing materials have attracted wide attention in gas sensing field. Here, we have fabricated Ru nanoparticles decorated Ti₃C₂T_x MXene (Ru@MXene) composite by an in-situ reduction method. By investigating the gas-sensitive characterizations of Ru@MXene, it can be seen that the sensor based on the Ru@MXene exhibits high response of ₂4 towards 50 ppm triethylamine at optimum working temperature. Moreover, the Ru@MXene sensor has outstanding repeatability and good long-term stability. These enhanced sensing properties can be ascribed to the catalytic activity and spillover effect from Ru nanoparticle, which can provide more active sites and accelerate gas sensing reactions. Therefore, this work offers a new idea for fabricating high-performance TEA sensors.
