Highlights Ultrasound enhances the phenolic compounds in extracted herbal oils by 44%. US (25–50 kHz) increases the yields of polyphenols, carotenoids, and flavonoids. Radicals generated by US have positive and negative effects on enzymes. US improves the efficiency of herbal extracts in Nanotechnology applications. Acoustic-based biosensors could be used for chemical imaging of herbal tissues.

“…Semiconductor photocatalyst has been used widely for the treatment of the water as compared to another conventional photocatalyst. [10][11] ZnO is having a wide bandgap with large excitation binding energy, which found for a large number of applications (UV laser, dye-sensitized solar cells, and gas sensing) by a virtue of its wide bandgap energy. The photocatalytic activity of ZnO gets restricted due to the expeditious rate of electron-hole recombination and lack of sunlight absorption.…”

The present study deals with the synthesis of ZnO and Ag‐ZnO nanoparticles using Excoecaria agallocha leaf extract under a controlled ultrasound cavitation technique. The characterization of the as‐synthesized ZnO and Ag‐ZnO nanoparticles (different molar concentration of Ag) were subjected to Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction analysis (XRD), UV‐Visible Diffuse reflectance spectroscopy (UV‐Vis DRS), Thermogravimetric analysis (TGA), N2 adsorption‐desorption isotherm (BET), scanning electron microscopy(SEM) and transmission electron microscopy (TEM). The photocatalytic performance of ZnO and Ag‐ZnO nanoparticles as catalysts were studied for hazardous organic dyes such as methylene blue (MB) and rhodamine‐B (Rh−B) under solar light irradiation. The degradation study follows pseudo‐first‐order kinetics. The effective degradation of MB was found to be 56.44 % (ZnO nanoparticles) and 98.44 % Ag‐ZnO nanoparticles, respectively at 100 min at the molar ratio (0.25 : 1). Whereas, Rh−B shows 27.50 % (ZnO nanoparticles) and 98.83 % at the same molar ratio of Ag‐ZnO nanoparticles at 80 min. Among the as‐synthesized nanoparticles, Ag‐ZnO at molar ratio 0.25 : 1 shows effective photocatalytic activity. Besides these as‐synthesized nanoparticles exhibited good antimicrobial activity with an increase in Ag nanoparticles decorated into ZnO. A similar trend was observed in antioxidant and anti‐inflammatory activity.

“…The Citrus aurantifolia peel extract has a high content of flavonoids (apigenin, hesperetin, kaempferol, nobiletin, quercetin and rutin), flavones, flavanones, naringenin, triterpenoids, and limonoids [24], which help in the synthesis of metal and metal oxide nanoparticles. Some authors have reported on the use of lemon and leaves extracts to obtain different types of nanoparticles, such as Ag:CdO nanocubes [25], ZnO [26], Ag [27,28], and Au [29]. At present, very few studies on the biosynthesis of SnO 2 nanoparticles have been carried out using plant extracts, for example, aqueous extracts of Papaya leaves [30], American persia [31], Litsea cubeba [32], and Aspalathus linearis [33] have been used for the synthesis of this material with photocatalytic applications.…”

This research presents an alternative tin oxide (SnO 2) nanoparticles synthesis method using different concentrations of Citrus aurantifolia peel extract as reducing agent. We report the chemical identification protocol for polyphenols in the peels via FTIR, the characterization of the SnO 2 nanoparticles by FTIR, XRD, HRTEM, and UV-vis. The SnO 2 nanoparticles presented the Sn-O-Sn bond at 640 cm −1 and crystal growth with a clearly tetragonal structure. Depending on the amount of extract used, hemispherical nanoparticles of different sizes (5-12 nm) and band gap values ranging from 3.02 to 3.44 eV were obtained. Photocatalytic degradation studies of the synthesized SnO 2 were carried out using methylene blue under UV light. The sample with 4% extract of C. aurantifolia showed a degradation rate of about 96% at 120 min. The use of C. aurantifolia as a reducing agent in the synthesis of SnO 2 nanoparticles helps the properties and has control over the morphology of the nanoparticles.
