As the demand for selective and sensitive gas sensors continues to escalate, development of novel materials with enhanced performance becomes increasingly imperative. The present investigation delves into fabrication implementation two-dimensional cobalt oxide (Co 3 O 4 ) nanostructures as highly proficient discerning identification hydrogen sulfide (H 2 S) within intricate environmental circumstances. distinct configuration Co , characterized by its substantial surface-to-volume ratio abundant accessible active sites, markedly augments adsorption reaction dynamics, resulting in exceptional sensitivity selectivity toward H S over other potentially confounding gases. Extensive characterization methodologies, encompassing X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), corroborate successful synthesis well-defined nanosheets. exhibited optimal detection at 250 °C, demonstrating significant (Response = 214.45) fast response recovery times (16.85 s 46.93 s, respectively). Its was further validated through concentration-dependent studies, which showed high accuracy even low concentrations (0.3–50 ppm). sensor also displayed excellent gases, minimal interference from humidity, maintained stability during cyclic exposure long-term operation 30 days. These findings highlight this material a promising due superior metrics. incorporation these nanosheets apparatus offers propitious strategy real-world applications, such surveillance industrial safety systems.
