Over the years, there has been an emphasis on the improvement of novel materials for photocatalytic processes for practical application in treating wastewater. In this sense, the ultrasonic-assisted in-situ chemical polymerization route was used to synthesize polypyrrole-multiwall carbon nanotubes (PPy-MWCNTs) nanocomposites. The transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and ultraviolet visible (UV-vis) analysis were employed to study the impact of MWCNTs on the properties of PPy. TEM showed that the PPy-MWCNTs nanocomposites consist of spherical PPy with 80 nm particle size, while the MWCNTs showed inner and outer diameters of 7 nm and 13 nm, respectively. XRD analysis showed that the crystallinity of the PPy increased with MWCNTs loading. The potential of PPy-MWCNTs nanocomposites as photocatalysts was evaluated via the photodegradation of rhodamine B (RhB) and methylene blue (MB) dyes. The photodegradation efficiency was found to have improved with increasing MWCNTs loading. Almost 99.36% and 78.30% of RhB and MB dye degradation were achieved after 35 min of reaction for the highest loading of MWCNTs. The remarkable nanocomposite photocatalytic activity was attributed to the optical bandgap energy (E g ) reduction with the addition of MWCNTs. These results foreshadow the potential use of the PPy-MWCNTs nanocomposites for water purification.

“…The presence of silver nanoparticles in phosphorus-containing cotton is confirmed by new peaks at 1452, 1438, 1353, and 608 cm −1 [ 30 , 36 ], and the peak at 519 cm −1 also confirmed the presence of Ag 2 O in the sample. In contrast to the silver-containing composite based on the original cotton, the cotton-(PO(OH) 2 )(Cl)-Ag sample has a clear peak at 874 cm −1 , which is attributed to AgCl [ 37 ]. This can be explained by the presence of C–Cl in the phosphorylated sample, which is also involved in the binding of silver nanoparticles.…”

In the present study, cotton fiber was treated with phosphorus trichloride in the presence of oxygen. As a result of the subsequent hydrolysis of modified cotton fibers, phosphorus-containing fragments with acidic groups and chlorine atoms were introduced onto their surface. Afterward, silver-containing composites based on raw and modified cotton fibers were prepared using the chemical reduction method. The obtained samples were characterized in detail by Fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, X-ray powder diffraction, as well as by thermogravimetric analysis, scanning electron microscopy, and energy-dispersive X-ray analysis. A comparative bioassay experiment of four samples for gram-negative (Escherichia coli) bacteria, gram-positive (Staphylococcus aureus) bacteria, and the fungus Candida albicans was carried out. These results showed the predominant antibacterial activity of the phosphorylated sample and the composite based on it. Thus, the development of these antibacterial cotton fibers using readily available reagents under relatively mild conditions could be used as potential industrial applications for the production of everyday medical textiles.

Nanotechnology is a fast-expanding area with a wide range of applications in science, engineering, health, pharmacy, and other fields. Among many techniques that are employed toward the production of nanoparticles, synthesis using green technologies is the simplest and environment friendly. Nanoparticles produced from plant extracts have become a very popular subject of study in recent decades due to their diverse advantages such as low-cost synthesis, product stability, and ecofriendly protocols. These merits have prompted the development of nanoparticles from a variety of sources, including bacteria, fungi, algae, proteins, enzymes, etc., allowing for large-scale production with minimal contamination. However, nanoparticles obtained from plant extracts and phytochemicals exhibit greater reduction and stabilization and hence have proven the diversity of properties, like catalyst/photocatalyst, magnetic, antibacterial, cytotoxicity, circulating tumor deoxy ribo nucleic acid (CT-DNA) binding, gas sensing, etc. In the current scenario, nanoparticles can also play a critical role in cleaning wastewater and making it viable for a variety of operations. Nano-sized photocatalysts have a great scope toward the removal of large pollutants like organic dyes, heavy metals, and pesticides in an eco-friendly and sustainable manner from industrial effluents. Thus, in this review article, we discuss the synthesis of several metal nanoparticles using diverse plant extracts, as well as their characterization via techniques like UV–vis (ultraviolet–visible), XRD (X-ray diffraction), SEM (scanning electron microscopy), TEM (transmission electron microscopy), FTIR (Fourier transform infrared spectroscopy), etc., and catalytic activity on various hazardous systems.
