Summary: In this study, Ti3C2Tx/CuO nanocomposites were successfully prepared through an environmentally friendly and simple hydrothermal method. The synthesized materials were characterized using various techniques, including XRD, SEM, TEM, XPS, FTIR, UV-vis, and BET. The results showed that Ti3C2Tx/CuO nanocomposites exhibited a mesoporous structure and a higher specific surface area compared to Ti3C2Tx, indicating the presence of more gas adsorption/diffusion regions. The introduction of CuO led to Ti3C2Tx having rich oxygen vacancies and adsorbed oxygen. The Ti3C2Tx/CuO sensor showed superior gas sensing performance, including a significantly higher response to 50 ppm NO2, ultra-fast response/recovery time, great reversibility, outstanding selectivity to NO2, and desirable long-term stability. The enhanced gas sensing performance can be attributed to the hybrid heterojunctions formed between CuO and Ti3C2Tx, which facilitate carrier migration and accelerate the redox reaction. The presence of more oxygen vacancies and adsorbed oxygen in Ti3C2Tx/CuO further enhances the gas sensing performance. These improved gas sensing performance indicators modified with CuO are expected to be advantageous for the development of Ti3C2Tx-based sensors for commercial NO2 detection in the future.

Summary: In this work, a ZnO1-x/Ti3C2 composite with rich oxygen vacancies was prepared by a hydrothermal process and subsequent annealing in a hydrogen atmosphere, showing high responses to low concentrations of NO2 at room temperature. The excellent sensing properties of the ZnO1-x/Ti3C2 composite are attributed to the presence of abundant oxygen vacancies and the formation of a ZnO1-x/Ti3C2 Schottky barrier. The composite also demonstrates high selectivity to NO2 compared to other gases. This study provides new insights into enhancing the room-temperature gas sensitivity of MOS-containing composites by constructing oxygen vacancies and heterojunctions.

Summary: Nanostructured transition metal oxides have gained much attention in gas sensing applications due to their superior size-dependent adsorption and catalytic properties. Pure and yttrium-doped WO3 nanoplates were prepared by one-step hydrothermal method and their gas sensing performance was studied. The Y-doped samples exhibited excellent selectivity towards NO2 and showed significantly enhanced gas sensitivity, response time, and recovery time compared to the pure sample. The enhancement in gas sensing performance has been explained by the gas sensing mechanism and work function measurement. Y-doped WO3 nanostructures provide a new pathway for improving the performance of transition metal oxide-based gas sensors.

Summary: Si@TiO2/Ti3C2Tx heterostructures were synthesized in situ from Ti3AlC2 MAX phase by combining high-temperature Si diffusion and HF etching. The optimal heterostructure showed semiconductor behavior with enhanced surface area due to the distribution of small TiO2 particles over Ti3C2Tx MXene. The heterostructure exhibited excellent 2,4-Dinitrophenol photodegradation and room-temperature NO2-sensing capabilities, with the photocatalytic degradation attributed to broad light absorption and efficient carrier separation by Schottky contact. Density-functional theory calculations suggested that Si atoms could facilitate NO2 adsorption, highlighting the multi-functionality potential of Si@TiO2/Ti3C2Tx heterostructure.

Summary: In this study, room temperature sensing of chloroform gas using SnO2 nanostructured thin films synthesized via a single-step ACVD process is demonstrated. Theoretical calculations and simulations show that chloroform molecules have a thermodynamically favorable adsorption on the SnO2 surface, leading to a drop in surface resistance and a sensing response.
