The need for efficient and reliable gas sensors has grown significantly due to increasing industrial activities, transportation, environmental pollution, posing serious risks human health the environment. Advanced sensor technologies are crucial detecting these harmful gases at low concentrations with a high accuracy. Nickel oxide, p-type metal oxide semiconductor, emerged as promising candidate sensing applications owing its unique excellent structural, electronic, catalytic properties along chemical stability. Interestingly, possibility synthesize NiO in versatile nanostructure forms: nanowires, nanoflowers, nanospheres, helps enhance surface area porosity, which critical factors improve adsorption diffusion. This review presents comprehensive assessment of latest advancements synthesis, characterization, gas-sensing performance nanostructures. We explore how structural modifications, such decoration noble nanoparticles, formation different composites, functionalization self-assembly sensitivity, selectivity, operational temperature sensors. Particular focus is given integration novel nanoheterostructures, where p-n p-p junctions improves charge transport overall response. Finally, we identify current challenges reproducibility, stability, operating conditions, while offering directions future research on tailoring nanostructures more effective, scalable, robust technologies.
