Abstract

fetched live from OpenAlex

The present study portrays a facile, cost-effective, and environmentally benign way for the preparation of TiO 2 nanoparticles utilizing C. limon extract, which possesses phytochemicals as reducing and stabilizing agents. Structural characterization by XRD reveals that C. limon /TiO 2 NPs exhibit anatase-type tetragonal crystallinity. An average crystallite-size is calculated using Debye Scherrer's method (3.79 nm), Williamson–Hall plot (3.60 nm), and Modified Debye Scherrer plot (3.68 nm), which are very closely intercorrelated. The absorption peak at 274 nm (UV–visible spectrum) corresponds to the bandgap (E g ) value of 3.8 eV. The existence of different phytochemicals containing organic groups like N–H, C=O, and O–H, has been elucidated from FTIR along with Ti–O bond stretching at wavenumber 780 cm −1 . Micro-structural investigations of TiO 2 NPs using FESEM and TEM display different geometrical configurations involving spherical, pentagonal, hexagonal, heptagonal and capsule-like structures. BET and BJH analysis show mesoporous characteristics of synthesized nanoparticles with specific surface-area (97.6 m 2 g −1 ), pore-volume (0.018322 cm 3 g −1 ), and mean pore-diameter (∼7.5 nm) values. In adsorption studies, the influence of reaction parameters, i.e., catalyst dosage and contact-time, for removal of Reactive Green dye is explored along with Langmuir and Freundlich models. The highest adsorption capability is ∼219 mg g −1 for green dye. TiO 2 displays an excellent photocatalytic efficiency of ∼96% towards the degradation of reactive green dye within 180 min and excellent reusable performance. C. limon /TiO 2 is found to have an outstanding performance with a quantum yield value of 4.68 × 10 −5 molecules photon −1 for Reactive Green dye degradation. Additionally, synthesized nanoparticles have exhibited antimicrobial activity against gram-positive Staphylococcus aureus ( S. aureus ) and gram-negative Pseudomonas aeruginosa ( P. aeruginosa ) bacteria.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.
