This study reports the synthesis of Fe?O? nanoparticles and Fe?O?/GO nanocomposites using a cold plasma jet technique, highlighting their structural, optical, and gas sensing properties. XRD, FE-SEM, and AFM analyses confirmed controlled crystallinity, nanoscale morphology, and enhanced surface features favorable for gas adsorption. Optical studies revealed tunable bandgaps and defect-related emissions linked to sensing activity. Gas sensing tests demonstrated high sensitivity and selectivity toward H?S and NO?, positioning these nanomaterials as promising candidates for efficient and eco-friendly gas sensors.
