Heliyon, Год журнала: 2023, Номер 9(2), С. e13484 - e13484

Опубликована: Фев. 1, 2023

In the present work, copper oxide (CuO NPs) was synthesized by an eco-friendly, simple, low-cost, and economical synthesis method using Ephedra Alata aqueous plant extract as a reducing capping agent. The biosynthesized CuO-NPs were compared with chemically obtained to investigate effect of preparation on structural, optical, morphological, antibacterial, antifungal, photocatalytic properties under solar irradiation. CuO NPs characterized X-ray diffraction (XRD), UV-VIS spectroscopy, Fourier transform infrared spectrometer (FTIR) analysis, field emission scanning electron microscopy energy dispersive spectroscopy (FESEM-EDX). activities biosynthetic prepared studied methylene blue upon exposure results showed that photocatalyst more efficient than for Methylene Blue (MB) degradation irradiation, MB rates 93.4% 80.2%, respectively. addition, antibacterial antifungal evaluated. disk diffusion technique used test against gram-negative bacteria, Staphylococcus aureus Bacillus subtilis, well C.

A pragmatic review on photocatalytic degradation of methyl orange dye pollutant using greenly biofunctionalized nanometallic materials: A focus on aquatic body

Applied Organometallic Chemistry, Год журнала: 2023, Номер 37(7)

Опубликована: Апрель 20, 2023

Water is the source of life. But unfortunately, 80% wastewater discharged into aquatic body untreated globally, which industry responsible for 70% such water abstraction through discharge pollutants like methyl orange. According to WWAP, pollution kills 100 million individuals, 2 marine animals, and seabirds yearly, by 2025, it forecasted that ~1000 inhabitants in arid zones will experience severe crisis, thus, security has become focal outcry due daily environmental escalation caused rapid growth industries population. Recently, biosynthesized nanoparticles as photocatalysts have answered call sustainable treatment orange dye effluent photodegradation because their efficient photoactivity, inexpensiveness, eco‐benignness. In this review, photocatalytic‐degradation mechanism pathways environment presence • OH − O using green were mechanistically discussed. The highest degradation efficiency was found be 100%, final mineralization products H CO , least time taken min with silver being most commonly used degrader plant extracts employed bioreductant biosynthesis nanoparticles.

Phytogenically bioengineered metal nanoarchitecture for degradation of refractory dye water pollutants: A pragmatic minireview

Applied Organometallic Chemistry, Год журнала: 2022, Номер 37(2)

Опубликована: Окт. 31, 2022

The present scenario of water insecurity (poor availability and accessibility to clean healthy when needed) denotes the preponderance environmental damage caused by effluents or waste runoff from industries, such as dye textile industries. polluted waters have led terrible sonorous negative impacts on ecosystem econetworking, thus, urging for a sustainably suitable substitute tackle annul noxious constraint posse hazardous effluent. Several chemical physical methods treating effluent are now in use, but they time‐consuming, expensive, inefficient. Interestingly, nanoparticles egressed superior answer efficient removal degradation, because their reactivity exceptional surface characteristics. As result, use metal nanomaterials treatment runoffs has been thoroughly investigated. study used major scientific databases SciFinder, Scopus, PubMed, Google Scholar, Science Direct conduct comprehensive review publicly available literature. Degradation, effluent, green nanoparticles, pollution were keywords find scholarly papers. Efforts made figure out explain mechanism how long degradation will take effective plant biosynthesized is. In addition, role bimetallic also investigated with remarkable feat current level knowledge about biogenic common is summarized this paper.

Review on green biomass-synthesized metallic nanoparticles and composites and their photocatalytic water purification applications: Progress and perspectives

Chemical Engineering Journal Advances, Год журнала: 2023, Номер 14, С. 100460 - 100460

Опубликована: Янв. 26, 2023

In recent years, the use of biomass for cost-effective synthesis nanoparticles has emerged as a promising green technology. Because their remarkable properties, such tunable surface plasmon resonance characteristics and high areas, bio-synthesised nanomaterials are receiving more scientific academic attention in various application sectors, especially catalysts environmental remediation. Green synthesized nanomaterial's can efficiently contribute to degradation wide range organic pollutants, including dyes, into harmless by-products. These particles have cure recalcitrant inorganic pollutants due photocatalytic which largely depend on production reactive oxygen species under sunlight or UV illumination. This comprehensive review systematically covers up-to-date knowledge developments composites using plants microorganisms, unravels underlying mechanisms, highlights areas. It then provides detailed information applications potentially toxic dyes removal other emerging heavy metals antibiotics. Finally, current challenges perspectives this technology future discussed.
