Toward Efficient Bactericidal and Dye Degradation Performance of Strontium- and Starch-Doped Fe 2 O 3 Nanostructures: In Silico Molecular Docking Studies
Abstract
High Resolution Image Download MS PowerPoint Slide In this study, various concentrations of strontium (Sr) into a fixed amount of starch (St) and Fe 2 O 3 nanostructures (NSs) were synthesized with the co-precipitation approach to evaluate the antibacterial and photocatalytic properties of the concerned NSs. The study aimed to synthesize nanorods of Fe 2 O 3 with co-precipitation to enhance the bactericidal behavior with dopant-dependent Fe 2 O 3 . Advanced techniques were utilized to investigate the structural characteristics, morphological properties, optical absorption and emission, and elemental composition properties of synthesized samples. Measurements via X-ray diffraction confirmed the rhombohedral structure for Fe 2 O 3 . Fourier-transform infrared analysis explored the vibrational and rotational modes of the O–H functional group and the C═C and Fe–O functional groups. The energy band gap of the synthesized samples was observed in the range of 2.78–3.15 eV, which indicates that the blue shift in the absorption spectra of Fe 2 O 3 and Sr/St-Fe 2 O 3 was identified with UV–vis spectroscopy. The emission spectra were obtained through photoluminescence spectroscopy, and the elements in the materials were determined using energy-dispersive X-ray spectroscopy analysis. High-resolution transmission electron microscopy micrographs showed NSs that exhibit nanorods (NRs), and upon doping, agglomeration of NRs and nanoparticles was observed. Efficient degradations of methylene…
How strong is the evidence?
Evidence Hub reads this as a experimental / empirical study, done in computer models (in silico), not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
