“…Numerous synthesis approaches, including co-precipitation [26,27], auto-combustion [28][29][30], one-step ion exchange method [31], thermal oxidation [32], electrochemical method [33], gas phase flame method [34], thermal decomposition [35], electrochemical deposition [36], sol-gel method [37], the ultrasound-assisted green method [38,39], the wet chemical method [40], have been used to synthesize semiconductor iron oxide materials. Some of these methods are unfriendly to large-scale practical applications because they often require the use of costly and harmful chemicals, prolonged reaction times, demanding conditions, and high temperatures.…”

Dye contamination is becoming a more significant environmental challenge with the development of the textile industry. Scientists from all over the world are working hard to create new, more efficient ways to reduce environmental pollution through environmentally friendly synthesis techniques. In this regard, hematite (α-Fe2O3) nanoparticles have been synthesized by the novel, quick, cheap, and environmentally safe microplasma technique for the photodegradation of rhodamine-B under direct sunlight. Thus, the synthesized α-Fe2O3 nanoparticles were characterized by various characterization techniques such as X-Ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), and ultraviolet-visible spectroscopy (UV-Vis spectroscopy). The structural and optical properties were found to vary with changing precursor concentrations. We measured the photocatalytic decolorization efficiency of synthesized hematite (α-Fe2O3) nanoparticles for rhodamine-B dye under direct sunlight. It was found that α-Fe2O3 nanoparticles exhibited a decolorization capability with 73.75% decolorization of the dye at the rate of 0.04305 g.mg-1.min-1 after 100 minutes of irradiation, exhibiting excellent performance to remove organic contaminants from wastewater.

<p>A technique for green manufacturing of zinc oxide based nanoparticles utilising cassava peel has been approached in this research for antibacterial investigation. Especially, the cassava peel is an agro waste from starch and food processing industries and the extract of Cassava peel is used for synthesising the zinc oxide nanoparticles (ZnO-NPs). The peel based zinc oxide nanoparticles were synthesized using bioreduction method. The plasmon peak from UV–Visible spectroscopy is observed at 380 nm, while the XRD shows an average crystallite size of 67.31nm with hexagonal structure and also the stability of bio synthesised nanoparticles are confirmed by FTIR study. Additionally, FESEM confirms the structure is found to be spherical whereas Zeta potential analysis has confirmed the nanoparticles have a stable and well-dispersed form. Furthermore, the anti bacterial study against bio synthesized ZnO-NPs is carried out for both gram positive and gram negative bacteria. Therefore, the results proved that the bacteria are found to be more active against the synthesized nanoparticles.</p>

The article describes synthesis of green‐mediated hematite nanoparticles (20–30 nm) using Polianthes tuberosa flower extract. Structural, microscopic, and magnetic studies confirm the synthesis of iron oxide nanoparticles of pure hematite phase. Spectroscopic techniques are employed to identify different electronic transitions and defect levels as well as to estimate the energy bandgap and Urbach energy. A correlation among the particle size, bandgap energy, and Urbach energy is noticed. These hematite nanoparticles act as visible light photocatalyst which degrade dye in aqueous medium without the addition of any additives. The catalyst particle size, catalyst quantity, pH of dye solution, and solution temperature have significant impact on the photodegradation process of dye molecules in aq. solution. All observations advocate that green synthesis of hematite nanoparticles with Polianthes tuberosa flower extract can significantly modulate their optical and photocatalytic properties. These materials may find potential uses in water splitting for hydrogen production and purification of water by removing organic pollutants. The study highlights that using commercially cheap starting materials and extract made from naturally available plant parts, materials having huge application potentials can be synthesized at low cost by the simple green synthesis approach.
