Synthesis of nanoparticles based on plant extract as reduction agent has been discovered extensively due to its environmental friendly approach. In this work, a facile silver nanoparticles is synthesized via incorporation of silver nitrate aqueous solution with Parkia speciosa leaves extract. Centrifugation is introduces to improve the characteristics of nanoparticles. Chemical interactions have identified –OH stretching vibration, C=O and C=C, proving the presence of phenolic, terpenoid and flavonoid capped on silver nanoparticles. The TEM result demonstrates the silver nanoparticles had consistence spherical nanoparticles shape with average particles size (59.96 nm) in accordance with FESEM analysis. The structural analysis by XRD shows the nanoparticles had high degree of crystallinity (97%) and crystallite size (17.95 nm). The optical analysis by UV‐Vis reveals that the nanoparticle produces brown colour solution with high absorption band (465 nm). This proves that Parkia speciosa extract has potential as reduction agent in synthesis of silver nanoparticles.

“…Goudarzi et al [96] For the production of nanoparticle silver, cochineal and pomegranate extracts were used, and the nanoparticle dispersion was well distributed. In the same way, Goudarzi et al [97] Silveralumina has a significantly high calibre efficiency. Cochineal powder has also been used to create nanocomposites.…”

N ATURAL dyes have been used for dyeing, painting, printing, and decoration since the dawn of time. However, with the manufacturing of synthetic dyes in the nineteenth century, it was revolutionised due to its extremely lasting properties and economic effectiveness. However, a new research highlights the negative implications of synthetic dyes, prompting people all over the world to reduce their use of synthetic dyes and focus on natural source colours, which have numerous advantages over synthetic dyes. These colours might be derived from animals, plants, minerals, or microorganisms. In this brief study, we will talk about natural colorants from an animal source and how to extract them using ancient and new methods that allow their counterparts to achieve equivalent properties.

“…27 Thus, various methods have been reported to synthesize silver alumina nano-powders. These methods including co-precipitation and impregnation method, 28 hydrothermal procedure, 29 sol-gel routes, via thermal drying (II) or freeze-drying, 30 solid-state thermal decomposition, 31 pulsed laser deposition, 32 and combustion synthesis. 33 Among them, combustion synthesis has reasonable advantages compared to other methods, including inexpensive and simple equipment required, simple preparation steps and short reaction time, multiplicity of usable fuels, high purity of products due to the impurities removal, chemical homogeneity of products and above all, it is a time and energy consuming manner.…”

In this research, Ag‐Al2O3 nanostructures have been prepared via combustion synthesis and ammonium acetate and urea have been applied as fuels. The prepared Ag‐Al2O3 nanostructures were characterized by DTA, XRD, SEM, TEM, and BET spectroscopy. The effect of different ratios of silver to alumina and fuel percentage on morphology and particle size of prepared products were investigated. The results showed that using ammonium acetate fuel led to the production of Ag‐γ‐Al2O3 nanocompounds, while using urea produced Ag‐α‐Al2O3. Also, the photocatalytic activity of Ag‐Al2O3 nanostructures for Congo red degradation was evaluated by UV‐Vis diffuse reflectance spectroscopy. The photocatalytic activity of Ag‐Al2O3 was examined under UV‐Vis irradiation and showed significant photocatalytic efficiency.
