Title: Microwave-assisted synthesis of tentacles like Ag-doped copper oxide nano-ceramics: Structural, optical, and anti-campylobacter studies
Abstract: The facile microwave approach has been adopted to successfully synthesize silver-doped CuO (ACO) and bare CuO (BCO) photocatalysts. Powder X-ray diffraction (PXRD), energy dispersive X-ray (EDX), field emission scanning electron microscopy (FESEM), optical absorption, current-voltage (I–V), and photoluminescence (PL) studies have been executed to evaluate the effects of silver doping on texture, microscopic characteristics, crystal structure, bandgap, electrical conductivity, and charge carrier separation. Nanostructured (nanorods) and narrow bandgap ACO photocatalyst was produced owing to the synergistic impact of surfactant-assisted synthesis and silver doping-induced bandgap regulation. The ACO photocatalyst was a better choice for antibacterial application than its counterpart (BCO photocatalyst) due to the induced characteristics that increased its specific surface area and light-harvesting capabilities. Photoinduced charge carriers (holes and free electrons) in the ACO photocatalyst are shown to separate at maximal extent according to the PL and I–V analyses, indicating their facile transport from the production site to the site of action. The synergistic effects owing to the tailored features enable the ACO photocatalyst to kill the Campylobacter bacteria and mineralize Acridine orange dye at a fast rate. The antimicrobial activity of the doped catalyst has a linear relationship with the applied catalyst dosage as the zone of inhibition (ZOI) increases from 14.2 mm to 22.7 mm when the ACO photocatalyst dosage was raised from 4 μg to 12 μg.
