2D V₂C MXene Based Flexible Gas Sensor for Highly Selective and Sensitive Toluene Detection at Room Temperature

ACS Applied Electronic Materials, Journal Year: 2024, Volume and Issue: 6(5), P. 3717 - 3725

Published: May 8, 2024

While the majority of reports on toluene gas sensors are rigid electrodes and based composite materials, doping with additional noble metals, or a high temperature detection method, this work is first demonstration vanadium carbide (V2C) MXene flexible room-temperature (RT) sensor. The V2C synthesized by an HF etching route. field emission scanning electron microscopy (FESEM) transmission (TEM) images exhibit typical accordion-like multilayered structure MXene, where Fourier-transform infrared spectroscopy (FTIR), Raman, X-ray photoelectron (XPS) data further ensured its successful growth. (band gap 3.9 eV) sensor employing polyester substrate, displays good reproducibility, quick response/recovery time (14 s/34 s), long-term stability, cross-selectivity, low limit 47.85 ppb over linear region 5–200 ppm at RT (27 ± 1 °C). effect relative humidity (RH) toward sensing has also been investigated here. This shows excellent response 775% 200 toluene, brilliant selectivity six other hazardous gases. sensor's plentiful surface functional groups (−F, −OH, −O) superior electrical characteristics responsible for enhanced performance. In light this, can be smart way to fabricate next-generation sensors.
