In the realm of NH3 gas-sensing applications, electrically conductive nature Ti3C2Tx MXene, adorned with surface terminations such as −O and −OH groups, renders it a compelling material. However, inherent challenges atmospheric instability selectivity in presence gas mixtures have prompted exploration innovative solutions. This work introduces strategic solution through deposition mixed-matrix membrane (MMM) composed poly(vinylidene fluoride) (PVDF) matrix zeolitic imidazolate framework-67 (ZIF-67) filler. composite acts selective filter, permitting passage specific gas, namely NH3. Leveraging hydrophobic chemically inert PVDF, MMM enhances stability by impeding water molecules from interacting MXene. Furthermore, ZIF-67 is to via acid–base interactions within zeolite group pore size. The sensor embedded filter exhibits modest 1.3% change sensing response 25 ppm compared without filter. result underscores filter's effectiveness conferring diffusivity, particularly at 35% relative humidity (RH) °C. Crucially, attributes PVDF impart heightened even amidst varying RH conditions. These results not only demonstrate effective detection but also highlight sensor's adaptability diverse environmental conditions, offering promising prospects for practical applications.

Recently, Ti3C2Tx MXenes have begun to receive attention in the field of gas sensors owing their characteristics high conductivity and abundant surface functional groups. However, Ti3C2Tx-based still suffer from drawbacks low sensitivity sluggish response/recovery speed towards target gases, limiting development further applications. In this work, Ti3C2Tx-ZnO nanosheet hybrids were fabricated through a simple sonication method. The exhibited short recovery time (10 s) under UV (ultraviolet) illumination, response (22 s), (367.63% 20 ppm NO2) selectivity. Furthermore, sensor has prominent anti-humidity properties, as well superior reproducibility multiple tests. active sites hybrids, including groups (-F, -OH, -O) oxygen vacancies ZnO, formation Schottky barriers between ZnO nanosheets rich photogenerated charge carriers together result excellent gas-sensing performance.
