Abstract Environmental contamination by hexavalent chromium (Cr(VI)) and antibiotic drug residues pose significant challenges to public health ecosystems. This study investigates the application of CoTiO 3 /BiVO 4 @MIL-Fe(53) (CT/BV@Fe-MOF) for reduction Cr(VI) degradation tetracycline (TCL) under visible light. After grafting an iron-based metal–organic framework MIL-Fe(53) on a modified composite, photogenerated electrons could easily be transferred from BiVO /Fe-MOF species via interfacial charge transfer. UV–vis diffuse reflectance spectroscopy showed that carriers were formed in response light absorption. The effect different operating parameters, including catalyst load, pH, initial Cr(VI), TCL concentration, was systematically evaluated during photocatalytic process. CT/BV@Fe-MOF composite exhibited 98.7% efficiency (50 ppm) 97.5% towards (30 within 90 min, resulting greater than pristine , Fe-MOF materials. displayed excellent stability over six cycles, highlighting its potential practical applications. In addition, plausible pathway using LC-ESI/MS analysis, while TEST program utilized investigate toxicity products generated

Abstract Ammonia is vital for industries, especially agriculture, where it used in fertilizers to boost crop yields. Globally, about 176 million tons of ammonia produced annually. Its synthesis relies on the Haber–Bosch process, which energy‐intensive (, 150 atm) and environmentally unsustainable. This has sparked considerable interest developing alternative, more sustainable approaches nitrogen fixation. One promising area research plasmonics. Plasmonics explores light interaction with nanomaterials, traditionally using noble metals like gold silver, are costly scarce large‐scale use. Alternative materials such as bismuth, aluminum, metal oxides exhibit plasmonics, providing a affordable solution industrial applications. Recent have focused optimizing these non‐noble plasmonic review offers in‐depth understanding plasmonics both metals. The then delves into mechanisms photocatalytic processes, particularly hot carrier generation, offering insights their role enhancing catalytic efficiency. Furthermore, highlights cutting‐edge fixation, emphasizing use alternative approach synthesis. Finally, identifies challenges, suggests solutions, sets stage advancing photocatalysis.

Опубликована: Фев. 19, 2025

Titania and reduced graphene oxide (rGO) are well-known materials with excellent photocatalytic properties, but research on the photocatalytic-based antibacterial effects of their combination remains limited. This study explored suitability titania nanotubes (TiO2 NTs) combined rGO two terminal functional groups (nonfunctional aminated (NH2)) as efficient photocatalysts for antimicrobial applications under visible light irradiation. Field-emission scanning electron microscopy observations revealed that covered entire surface TiO2 NTs. Tauc plots calculated from spectra diffuse reflectance spectroscopy showed band gaps nonfunctional amine rGO-coated NTs were 2.40 2.21 eV, respectively. Therefore, all exhibited activity 470 nm An colony forming unit test using S. aureus P. aeruginosa, enzymatic tests (superoxide dismutase catalase) same bacteria, visible-light irradiation compared to uncoated groups. In addition, MTT assay enhanced cell viability after visible-light-triggered has significant potential expressing properties in dental applications.
