High Sensitivity BiO/TiCT Ammonia Sensor Based on Improved Synthetic MXene Method at Room Temperature.

The MXene TiCT was synthesized using hydrofluoric acid and an improved multilayer method in this study. Subsequently, a BiO/TiC2T composite material was produced through hydrothermal synthesis. This composite boasts a unique layered structure, offering a large surface area that provides numerous contact and reaction sites, facilitating the adsorption of ammonia on its surface.

α-FeO/TiO/TiCT Nanocomposites for Enhanced Acetone Gas Sensors.

Metal oxide semi-conductors are widely applied in various fields due to their low cost, easy processing, and good compatibility with microelectronic technology. In this study, ternary α-FeO/TiO/TiCT nanocomposites were prepared via simple hydrothermal and annealing treatments. The composition, morphology, and crystal structure of the samples were studied using XPS, SEM, EDS, XRD, and multiple other testing methods.

Highly selective NH gas sensor based on Co(OH)/TiCT nanocomposites operating at room temperature.

Ammonia (NH) is a common air pollutant and is a biomarker for kidney disease. Therefore, the preparation of ammonia gas sensors with high sensitivity, good selectivity and low operating temperature is of great importance for health protection. Using the electrostatic self-assembly approach, a chemoresistive gas sensor based on Co(OH)/TiCT hybrid material was created in this study.
