Abstract This study aimed to evaluate the concept of green synthesis metallic nanoparticles (silver nanoparticles, AgNPs) by plant extracts without using any toxic or hazardous materials. Alchemilla vulgaris (AV) and Helichrysum arenarium (HA) are used as capping reducing agents synthesize AgNPs (as coded AV-AgNPs HA-AgNPs). Both synthesized were characterized UV–visible spectrophotometry, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), transmission electron microscope (TEM). The results characterization exhibited that successfully synthesized. They highly well-dispersed, mostly spherical shape with an average size 15–20 nm. Catalytic reduction methylene blue (MB) 4-nitrophenol (4-NP) was assessed nano-catalysts in presence NaBH 4 . catalytic activity revealed significant terms degradation MB 4-NP 4-AP (4-aminophenol). reactions happen within 6–7 min HA-AgNPs According reusability analysis, demonstrated excellent performances more than 94% removal efficiency maintained after five reuse cycles. In addition, antibacterial activities investigated against Escherichia coli ( E. ; Gram-negative bacteria) Staphylococcus aureus S. Gram-positive quantitative well-diffusion method inhibition zones determined Mueller–Hinton agar (MHA) media. showed strong zone diameters 25.5 25 mm, respectively. also extremely effective on high values 22 24 Finally, fabricated silver could be candidates for separation

Compact Disc-Derived Nanocarbon-Supported Catalysts with Extreme Catalytic Activity

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Янв. 22, 2025

Advanced carbon–metal hybrid materials with controllable electronic and optical properties, as well chemical reactivities, have attracted significant attention for emerging applications, including energy conversion storage, catalysis environmental protection. However, the commercialization of these is hampered by several vital problems, energy-intensive synthesis expensive chemicals, inefficient control their structures properties. Herein, we report simple engineering nanocarbon–metal self-assembled silver nanocatalysts (SSNs) derived from polycarbonate (PC)-based discs using microplasmas under ambient conditions. The plasma-engineered catalysts exhibited controlled properties surface functionalities, hydrophilicities, Ag+/Ag0 metallic states, Ag loading. synthesized leverage localized plasmon resonance (LSPR) enabling enhanced catalytic activity rapid reduction carcinogenic 4-nitrophenol (4-NP) to valuable pharmaceutical intermediate 4-aminophenol (4-AP), achieving a high reaction rate constant 0.2 ± 0.0 s–1 completing in just 30 s. Demonstrating robust performance, SSNs maintained up 90% efficiency after ten recycling cycles, underscoring stability reusability. This work not only presents an effective approach upcycling disc waste, but also highlights potential remediation, offering low-energy solution high-efficiency pollutant reduction.
