Synthesis of nanoparticles composed of silver and silver chloride for a plasmonic photocatalyst using an extract from a weed Solidago altissima (goldenrod)

Abstract

Phytosynthesis of nanomaterials is advantageous since it is economical, ecofriendly, and simple, and, what is more, in the synthetic protocols, nontoxic chemicals and biocompatible materials are used. Here, a green synthetic methodology of nanoparticles (NPs) composed of silver (Ag) and silver chloride (AgCl) NPs is developed using a leaf extract of Solidago altissima as a reducing agent for the first time. Utilization of a terrestrial weed for the synthesis of Ag and AgCl NPs is a novel environmentally friendly approach considering that no toxic chemicals, external halide source, or elaborate experimental procedures are included in the process. The optical properties and elemental compositions of as-synthesized Ag and AgCl NPs are well characterized, and the degradation of an organic dye, i.e., rhodamine B (RhB), is investigated using the Ag and AgCl NPs. We find that degradation of RhB is effectively achieved thanks to both surface plasmon resonance and semiconductor properties of Ag and AgCl NPs. The surface-enhanced Raman scattering and antibacterial activities are also examined. The present approach to the synthesis of NPs using a weed may encourage the utilization of hazardous plants for the creation of novel nanomaterials.

Antimicrobial, Antioxidant, and Anticancer Activities of Biosynthesized Silver Nanoparticles Using Marine Algae Ecklonia cava

“…The formation of AgCl NPs might be attributed to the interaction of silver ions with chloride ions present in aqueous extract of Ecklonia cava . Similar results have been previously reported regarding the biosynthesis of AgNPs [ 75 , 78 ].…”

“…It is in agreement with several studies that have reported similar XRD patterns of biosynthesized AgNPs [ 59 ]. It was found that other co-existing peaks at 2θ values of 28.0°, 32.5°, 46.4°, 55.1°, and 57.5° correspond to (1 1 1), (2 0 0), (2 2 0), (3 1 1), and (2 2 2) planes of face-centered cubic crystalline phase of silver chloride, respectively (JCPDS file: 31-1238) [ 75 , 76 , 77 , 78 , 79 , 80 ]. This result clearly indicates the production of Ag/AgCl composite nanoparticles (Ag/AgCl NPs) using aqueous extract of Ecklonia cava .…”

“Smart” Antimicrobial Nanocomplexes with Potential to Decrease Surgical Site Infections (SSI)

“…These findings confirm the semicrystalline nature of the silver nanoparticles. Additionally, there is very weak peak for AgCl at 2θ = 27.4 • for (200), which is reported by Kumar et al and Hamed et al as well [99,100]. The XRD analysis of the nanocompounds TCA-AgNPs-PI and Cinn-AgNPs-PI indicated both amorphous and crystalline regions [101].…”

Biosynthesis of Silver Nanoparticles from Persimmon Byproducts and Incorporation in Biodegradable Sodium Alginate Thin Film

“…Chlorine could have originated from the chlorine containing phytochemicals present in the persimmon byproducts. Several other studies have demonstrated chlorine in EDX spectra (Gou and others ; Kumar and others ). The average particle sizes of NPs determined by DLS were 120 nm for seed, 94 nm for peel and 118 nm for calyx.…”
