Carbon dioxide emissions pose a significant threat to human health and the environment, necessitating improvements in CO 2 sensing devices. Current infrared detection sensors are complex large, limiting their practical applications due high-power consumption large size. To overcome this problem, we report herein -sensitive Bi O 3 /Ti C T x film based device fabricated using drop casting method. As-synthesized materials were analyzed for crystal structure size, surface morphology, composition XRD, SEM, EDS, UV-visible spectroscopy. The nanoparticles decorated on of Ti MXene sheets resulting formation nanocomposite. At room temperature, nanocomposite exhibits sensor response 1.43 at 250 ppm, which is better than pristine i.e. 1.35 same concentration ppm. When was exposed ppm , it exhibited recovery times 6.01 s 8.52 s, respectively. showed excellent selectivity good repeatability. This improvement junction interface nanocomposite, explained with detailed mechanism. These exceptional performances highlight potential gas applications.

This research enhances ethanol sensing with Fe-doped tetragonal SnO2 films on glass, improving gas sensor reliability and sensitivity. The primary objective was to improve the sensitivity operational efficiency of sensors through Fe doping. were synthesized using a flexible adaptable method that allows for precise doping control, energy-dispersive X-ray spectroscopy (EDX) confirming homogeneous distribution within matrix. A morphological analysis showed surface structure ideal sensing. results demonstrated significant improvement in response (1 20 ppm) lower temperatures compared undoped sensors. exhibited higher sensitivity, enabling detection low concentrations showing rapid recovery times. These findings suggest interaction between molecules surface, performance. mathematical model based diffusion porous media employed further analyze optimize considers matrix, considering factors such as morphology concentration. Additionally, choice electrode material plays crucial role extending sensor’s lifespan, highlighting importance selection design.
