Summary: 2D MXene materials offer the opportunity to manufacture ceramic composites with special structures and functions. By carefully designing and implementing strategies to maintain a complete layered structure and control the exfoliation of MXene sheets, as well as ensuring homogeneous distribution, we can achieve improved mechanical properties and self-monitoring capabilities in the composite materials. The conductivity related to the spatial distribution of MXene sheets enables the composite to potentially be used for smart structural and functional applications.

Summary: In this article, a gas sensor based on metal organic frameworks (MOFs) derived In2O3/Ti3C2Tx MXene was reported. The In2O3 microstructures were successfully anchored on the surface of Ti3C2Tx MXene, resulting in a sensor with excellent performance. The experimental results showed that the sensor exhibited high response rate and low detection limit towards NH3 gas, and demonstrated excellent linear response, fast response/recovery rate, outstanding selectivity, and stability. This research is expected to be an important reference for the design of high-performance ammonia gas sensors.

Summary: Three-dimensional hierarchical Cu2O-CuO microflowers assembled by nanorods were synthesized through an environmentally friendly hydrothermal route. The Cu2O-CuO microflowers-2 sensor exhibits excellent selectivity, repeatability, and long-term stability to NO2, with fast response and recovery time, even under high humidity conditions. Such superior sensing properties can be attributed to its unique structural advantages, more surface adsorbed oxygen, and the synergistic influence between the two-phase coexistence.

Summary: In this study, Ti3C2Tx with oxygen-rich functional groups and Ag-loaded Ti3C2Tx were successfully fabricated by the reuse of oxidized Ti3C2Tx. Experimental results showed that Ag-loaded Ti3C2Tx exhibited better sensitivity to NH3 and humidity resistance compared to single/few-layer Ti3C2Tx. Simulation results demonstrated that Ag-loaded Ti3C2Tx had less degradation in response to humidity changes and the Ti atom on the Ti3C2O2 surface contributed to the gas sensing performance. Furthermore, the formation of heterojunction between Ag and Ti3C2Tx improved the gas-sensing response.
