Green production of biologically active Ag and Ag–Cu nanoparticles from Prosopis cineraria pod waste extract and their application in epoxidation

The main focus of the current research is bio-nano-technologically produced nanoparticles (NPs) utilizing waste materials. There a need for developing advanced technology to reduce in an eco-friendly way. Therefore, presently discarded aqueous portion Prosopis cineraria pod was used after boiling, synthesize Ag and Ag–Cu NPs. FT-IR spectra illustrated presence phenyl propenoids flavonoids displaying capping as well reducing properties. TEM SEM imaging exhibited average size NPs (14 nm) (27 nm). crystallinity nature confirmed by XRD, Cu validated through energy-dispersive X-ray analysis. According antimicrobial data, Saccharomyces cerevisiae displayed zone inhibition (ZOI) 42.85% (Ag NPs) 33.98% (Ag–Cu at lower concentrations (0.0321 mg/ml), while Bacillus subtilis found most susceptible (85% ZOI) 0.5 mg/ml concentration. Further, these Ag–Cu) were utilized epoxidation alkene moieties. showed conversion (65%), very active linalool (93% conversion), suggesting Cu-facilitated epoxidation. To best our knowledge first time, applied prepare green that can be agents synthesis platform chemicals (epoxide) industrial aspects. These inexpensive ways producing have been several times potential applications nano-medicine, therapeutics, modification monoterpenoids fine fragrance.
