摘要: Coupling of layered semiconductors with graphene-based materials could enable enhanced performance as compared to the pristine counterparts. Herein, we report multifunctional behaviour a bismuth oxyiodide–graphene oxide (BiOI–GO) composite regarding its field emission and photocatalytic characteristics. The oxyiodide (BiOI) nanodiscs nanostructured BiOI–GO were synthesized at room temperature employing facile, single step precipitation method. as-synthesized products characterized using XRD, SEM, TEM, Raman spectrophotometer so reveal their phase, morphological structural properties. Field (FE) studies BiOI nanocomposite emitters carried out base pressure ∼1 × 10−8 mbar. values turn on required draw an current density 10 μA cm−2 are found be 2.7 1.2 V μm−1 for emitters, respectively. Extraction ∼1150 from emitter remarkably low applied 2.8 signifies FE performance. superior characteristics attributed modulation electronic properties due formation, high aspect ratio nanosheets/nanodiscs. Furthermore, exhibits activity towards degradation methyl orange (MO) dye.
