Dual-functionality of terbium-doped MoO3 semiconductor nanomaterials for degradation of synthetic textile dyes and antimicrobial activity
Terbium-doped MoO3 (Tb/MoO3) nanoparticles were synthesized via a green method using Adenanthera pavonina leaf extract. Structural, optical, and morphological properties were investigated using X-ray diffraction, Fourier-Transform Infrared, Thermogravimetric, UV-Visible Diffuse Reflectance Spectroscopy, Transmission Electron Microscopy, Scanning Electron Microscopy – Energy Dispersive X-ray, and X-ray Photoelectron Spectroscopy analyses. TEM images revealed agglomerated spherical particles with an average size of ~19 nm. Tb doping reduced crystallinity and narrowed the band gap to 2.1 eV, enhancing visible light absorption. Photocatalytic degradation of Congo red, Brilliant green, and Nile blue A dyes achieved efficiencies of 87.6%, 90.8%, and 86.4% respectively within 120 min, following pseudo-first-order kinetics. Antibacterial studies showed strong inhibition against Staphylococcus aureus and Pseudomonas aeruginosa, with zones up to 20 mm, attributed to ROS-mediated membrane disruption. The catalyst retained ~80% efficiency after five reuse cycles. These findings confirm the dual-functional potential of Tb/MoO3 for sustainable wastewater treatment and antimicrobial applications.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
