Abstract Cobalt-doped zinc oxide nanoparticles were fabricated and examined in this study as a potential photocatalyst for the antibiotic ciprofloxacin (CIPF) degradation when exposed to visible LED light. The Co-precipitation technique created that 5, 10, 15% Co-loaded. Different known techniques have been used characterize synthesized ZnO cobalt-doped nanoparticles. Compared other nanoparticles, experiments showed 10% very effective catalyst CIPF photodegradation. According XRD, these NPs hexagonal Wurtzite structure with an average size of between 38.47 48.06 nm. Tauc plot displayed optical energy band-gap (3.21) slowly declines Co doping (2.75 eV). enhanced photocatalytic activity which avoids electron-hole recombination, is brought on by implantation Co. Within 90 min, 30 mg/L solution was destroyed (> 99%). kinetics studies demonstrated first-order model, R 2 = 0.9703, appropriate illuminating pace reaction quantity elimination. recycled performance toward 3 cycles same efficiency. Furthermore, optimization using Central composite design (CCD) also studied. optimal parameters pH 6.486, 134.39 rpm shaking speed, 54.071 mg dose, 31.04 ppm initial concentration resulted highest efficiency (93.99%). Artificial neural networks (ANN) simulate experimental data. backpropagation train 152 input-output patterns. After experimenting various configurations, best results correlation value ( ) 0.9780 data validation obtained three-hidden layered network included five, eight neurons, respectively.

Abstract Unique magnetically recoverable copper/zinc-doped hematite nanoparticles, were synthesized by using a co-precipitation process with polymer polyvenylpyrodine and an aqueous extract of the Azadirachta indica plant serving as capping stabilizing agent. Hematite nanoparticles are most stable form iron oxide at room temperature, presented work concentrated on effects comparisons chemically green doped materials that serve dual role reducing agents: supporting biomedical application catalyzing environmental cleanup through photocatalysis. The prepared characterized X-ray diffraction, UV–vis spectroscopy, Fourier-transform infrared Raman vibrating-sample magnetometry, scanning electron microscopy, transmission microscopy techniques to examine produced material. average grain size for was found be 13.33–19.90 nm based diffraction measurements. spectroscopy spectrum demonstrates function biomolecules in nanoparticles. ferrimagnetic character demonstrated Vibrating-sample magnetometer investigation showed dependence 300 K. According phytochemical study, A. has components enhance its photocatalytic antioxidant activity. In comparison, chemical/green noticeably higher activity oxidative breakdown hazardous organic dyes Rhodamine blue Congo red. Additionally, photocatalyst displayed outstanding stability reaction. Radical scavenger assays 2,2-diphenyl-1-picrylhydrazyl 2,2′-Azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) used measure capability. Based assay, bran husk fractions levels This research is regarded novel step production particular biological characteristics wide use environmental, agricultural areas.
