“…HR-TEM was used to ascertain the sizes, shapes, and crystalline makeup of the phytofabricated NPs, and the resulting electron micrographs exhibit that the Semal-ZnO NPs are spherical with an average size of 17 nm (Figures 3A,B,E), which is in line with the findings of some recent literature (Kamaraj et al, 2022;Sreelekshmi et al, 2023;Tejaswini et al, 2023;Yassin et al, 2023). The micrographs show a homogeneous distribution, but agglomeration of the Semal-ZnO NPs was also visible (Abdullah et al, 2023;Meena et al, 2023), probably owing to the elevated surface energy of the NPs and chemical makeup of the surfacebound capping and reducing agents (Abdullah et al, 2023).…”

This work successfully demonstrates a sustainable and environmentally friendly approach for synthesizing Semal-ZnO nanoparticles (NPs) using the aqueous leaf extract of Bombax ceiba L. These NPs exhibit an absorption peak at approximately 390 nm in the UV-visible spectrum and an energy gap (Eg) of 3.11 eV. Detailed analyses of the morphology and particle size using various spectroscopic and microscopic techniques, XRD, FE-SEM with EDS, and HR-TEM reveal crystallographic peaks attributable to the hexagonal phase, with an average crystal size of 17 nm. The Semal-ZnO NPs also exhibit a notable photocatalytic efficiency for degrading methylene blue (MB) and methyl orange (MO) under sunlight in different water samples collected from diverse natural sources, indicating that they are promising photocatalysts for environmental remediation. The photocatalytic efficiency of the biofabricated Semal-ZnO NPs is impressive, exhibiting a photodegradation rate of up to 99% for MB and 79% for MO in different water samples under exposure to sunlight. The novel phytofabricated Semal-ZnO NPs are thus a beacon of hope for the environment, with their desirable photocatalytic efficiency, pseudo-first-order kinetics, and ability to break down noxious dye pollutants in various aquatic environments.

“…There is a plethora of effective research on the use of nanoparticles to reduce 4-nitrophenol. Metal nanoparticles have many uses in the biological, electrochemical, and medicinal domains because of their distinctive features, such as substantial surface area relative to volume ratios and signi cant surface energies related to their bulk molecules [4][5][6][7]. There are various types of metal oxide nanoparticles, but copper oxide nanoparticles are of particular interest due to their potential for usage in both science and industry.…”

Recently, the role of plant-based nanoparticles as sustainable catalysts has emerged as a new eld in material science. As a result of their wide applicability, bio-designed nanocatalysts have dominated the present study. At this juncture, this study gives the rapid and systematic procedure for the formation of an aqueous Elaeocarpus Sylvestris plant leaf extract capped Copper Oxide nanoparticles (ESCuO NPs). A benign method has been established for the fabrication of ESCuO nanoparticles that which serves as an innocuous, renewable, and mild reducing agent. Vivid spectrochemical and optical experimental investigation supported the formation of the ESCuO particles. Based on TEM investigation, the produced ESCuO NPs had spherical shape and an average size of 53 nm. The phytochemicals were used as a reducing agent internally without the use of harmful chemicals or extremely high temperatures. The derived ESCuO NPs have been employed as a powerful catalyst to reduce 4-nitrophenol. Further, rate constants for different doses were calculated. The antioxidant e ciency of synthesised ESCuO NPs was determined. This study illustrates the way for cutting-edge synthesis of CuO NPs with numerous applications.
