It is urgent to develop an ultrasensitive formaldehyde (HCHO) sensor that can operate at room temperature and has a low detection limit. Metal oxide semiconductors are excellent gas sensitive materials. Therefore, in this paper, we present the synthesis of fluorine (F) doped zinc (ZnO) porous nanomaterials through straightforward one-pot method with optimization F doping levels achieve concentrations HCHO under UV light temperature. Under 375 nm light, exhibits response value 386% 10 ppm HCHO, which 2.6 times higher than pure ZnO, its limit as 75 ppb. selectivity, stability, moisture resistance, meet requirements daily life. Analysis reveals ZnO not only increases material's specific surface area but also introduces active sites. Furthermore, it alters state on from physical adsorption chemical adsorption. The above reasons together enhance material, thereby improving sensitivity performance. Overall, work demonstrates F-doped potential material for sensors provides insights into interpretation effect properties

Perovskite oxide-based materials (ABO3) have gained much attention as promising candidates for advanced gas-sensing applications due to their versatile structures, tunable properties, and excellent stability. This review discusses recent developments in the synthesis, structural optimization, functionalization of perovskites enhance performance. Strategies such doping, creating oxygen vacancies, tuning morphology, forming heterojunctions significantly improved sensitivity, selectivity, response, recovery times. Specific advances include incorporation nanostructures, porous morphologies, catalytic elements, which optimized adsorption desorption processes various target gases, including volatile organic compounds, NO2, CO2. Mechanistic insights into role surface defects, charge carrier dynamics are also addressed. These position perovskite important components next-generation gas sensors environmental monitoring industrial applications.
