“…In the past two decades, noble metal nanoparticles (MNPs), especially silver (AgNPs) and gold nanoparticles (AuNPs), have increasingly attained great attention from the scientific community as well as society due to their distinctive biological, physical, chemical, and optical properties [1,2]. They have found many applications in diverse areas, such as electronics [3], biotechnology [4,5], beauty care products [6], drug delivery [7,8], biosensing, and catalysis [9,10].…”

“…One of the most important criteria for the selection of a suitable plant is that the plant (i) should be friendly to people, (ii) should have potential biomolecule classes acting as effective stabilizing agents for preventing the agglomeration of the formed MNPs, and (iii) should not affect the properties of MNPs by masking their surface [2,29]. Furthermore, plant sources containing phytochemicals of known nature are advised as better precursors for the MNP synthesis than an unknown [13].…”

This study describes a simple green method for the synthesis of Limnophila rugosa leaf-extract-capped silver and gold nanoparticles without using any expensive toxic reductant or stabilizer. The noble metal nanoparticles were characterized by Fourier transform infrared (FTIR) microscopy, powder X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray analysis (EDX), high-resolution transmission electron microscopy (HR-TEM), selected area electron diffraction (SAED), and dynamic light scattering (DLS) method. It has been found that the biosynthesized silver and gold nanoparticles are nearly spherical in shape with a mean particle size distribution of 87.5 nm and 122.8 nm, respectively. XRD and SAED patterns confirmed the crystalline nanostructure of the metal nanoparticles. FTIR spectra revealed the functional groups of biomolecules presented in the extract possibly responsible for reducing metallic ions and stabilizing formed nanoparticles. The biosynthesized metal nanoparticles have potential application in catalysis. Compared to previous reports, Limnophila rugosa leaf-extract-capped silver and gold nanoparticles exhibited a good catalytic activity in the reduction of several derivatives of nitrophenols including 1,4-dinitrobenzene, 2-nitrophenol, 3-nitrophenol, and 4-nitrophenol.

“…However, the drawbacks of physical and chemical methods may be the low production efficiency, requirement of expensive equipment, usage of toxic reductants, and the long-time reaction, which might affect the cost of obtained products [4]. Compared with the traditional chemical methods, biogenic synthesis of AgNPs and AuNPs using herbal plant extracts is an ecofriendly solution due to its sustainable nature and environmentally benign [5]. The first use of plant extract for the synthesis of MNPs was recorded by Gardea-Torresdey et al in 2003 [6].…”

“…Concerning catalytic activity, recent studies show that AgNPs and AuNPs possess a good catalytic performance in the transformation of toxic nitrophenolic compounds into useful aminophenols [5]. Among various derivatives of nitrophenols, 2-nitrophenol (2-NP) and 3-nitrophenol (3-NP) are often found in the textile industrial wastewater as well as the agricultural [30].…”

The green biosynthesis of metal nanoparticles (MNPs) has been proved to have many advantages over other methods due to its simplicity, large-scale production, ecofriendly approach, and high catalytic efficiency. This work describes a single-step technique for green synthesis of colloidal silver (AgNPs) and gold nanoparticles (AuNPs) using the extract from Caulis Spatholobi stems. Ultraviolet-visible spectroscopy measurements were used to optimize the main synthesis factors, including metal ion concentration, reaction time, and reaction temperature via surface plasmon resonance phenomenon. Fourier-transform infrared spectroscopy showed the possible functional groups responsible for reducing and stabilizing the synthesized MNPs. The powder X-ray diffraction and selected area electron diffraction analysis confirmed the crystalline nature of the biosynthesized MNPs. High-resolution transmission electron microscopy revealed the spherical shape of MNPs with an average size of 10-20 nm. The obtained MNPs also exhibited the enhanced catalytic activity in the reduction of 2-nitrophenol and 3-nitrophenol.

“…Among the limited literature data devoted to a comparative analysis of the catalytic transformation of the nitrophenol isomers, it is concluded that their reduction can be dramatically affected by the nature of the isomer molecule and the catalyst (composition, morphology, texture, etc.). [20][21][22][23][24][25][26]33] The comparison of the catalysts efficiency in reducing o-NP, m-NP, and p-NP nitroaromatic isomers is barely explored in the literature. Thus, in the present work, the effect of OHÀ substituent position was studied in detail in the catalytic reduction of o-NP, m-NP and p-NP molecules using Ag/ZA4 as a catalyst prepared by ion exchange or microwaved-assisted methods.…”

Catalytic Transformation of Positional Nitrophenol Isomers on Highly Active Ag/Linde‐Type A4 Zeolite: A Comparative Analysis

et al. 2023

The catalytic transformation of ortho-(o-NP), meta-(m-NP) and para-nitrophenols (p-NP) by Ag nanoparticles (Ag-NPs) stabilised on zeolite A4 (ZA4) is presented for the first time. The catalysts are prepared by microwave-assisted synthesis (Ag/ZA4-MW) or ion exchange (Ag/ZA4-IE). The results indicate that the nitrophenol reduction rate depends on the molecule structure and the presence of low-coordinated metallic Ag-NPs (~2 nm and sub nanometric species). Meanwhile, the reactivity tendency depends on the synthesis methodology (m-NP > p-NP > o-NP and o-NP > m-NP > p-NPfor Ag/ZA4-MW and Ag/ZA4-IE, respectively). The turnover frequency (TOF) values estimated for nitrophenols reduction are superior for Ag/ZA4-MW catalyst by several orders of magnitude compared with those obtained for Ag/ZA4-IE catalyst. In addition, the catalyst exhibits remarkable catalytic stability for the reduction of p-NP even after the fifth consecutive catalytic run. The presently prepared catalysts are characterised by superior catalytic activity for the reduction of nitroaromatic compounds than similar Ag-based materials reported in the literature.
