This study presents the fabrication and characterization of highly selective, room-temperature gas sensors based on ternary zinc oxide–molybdenum disulfide–titanium dioxide (ZnO-MoS2-TiO2) nanoheterostructures. Integrating two-dimensional (2D) MoS2 with oxide nano materials synergistically combines their unique properties, significantly enhancing sensing performance. Comprehensive structural chemical analyses, including scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Raman spectroscopy, Fourier transform infrared (FTIR), confirmed successful synthesis composition The demonstrated excellent selectivity in detecting low concentrations nitrogen (NO2) among target gases such as ammonia (NH3), methane (CH4), carbon (CO2) at room temperature, achieving up to 58% sensitivity 4 ppm 6% 0.1 for NO2. prototypes outstanding a short response time approximately 0.51 min. impact light-assisted enhancement was examined under 1 mW/cm2 weak ultraviolet (UV), blue, yellow, red light-emitting diode (LED) illuminations, blue LED proving deliver highest sensor responsiveness. These results position ZnO-MoS2-TiO2 nanoheterostructures sensitive selective NO2 that are suitable applications environmental monitoring, public health, industrial processes.
