Environmental problems with chemical and biological water pollution have become a major concern for society. Providing people with safe and affordable water is a grand challenge of the 21st century. The study investigates the photocatalytic degradation capabilities of hydrothermally prepared pure and Cu-doped ZnO nanoparticles (NPs) for the elimination of dye pollutants. A simple, cost-effective hydrothermal process is employed to synthesize the Cu-doped ZnO NPs. The photocatalytic dye degradation activity of the synthesized Cu-doped ZnO NPs is tested by using methylene blue (MB) dye. In addition, the parameters that affect photodegradation efficiency, such as catalyst concentration, starting potential of hydrogen (pH), and dye concentration, were also assessed. The dye degradation is found to be directly proportional to the irradiation time, as 94% of the MB dye is degraded in 2 hrs. Similarly, the dye degradation shows an inverse relation to the MB dye concentration, as the degradation reduced from 94% to 20% when the MB concentration increases from 5 ppm to 80 ppm. The synthesized cost-effective and environmentally friendly Cu-doped ZnO NPs exhibit improved photocatalytic activity against MB dye and can therefore be employed in wastewater treatment materials.

“…One such vegetable waste is onion, i.e., onion waste, which is commonly generated in every house, especially in a country like India. Onion is considered to have numerous phytochemicals, flavonoids, and enzymes that help in the synthesis of nanoparticles [ 17 , 18 , 19 ]. Alamdari et al, 2020 reported the synthesis and characterization of ZnONPs by using leaf extract of Sambucus ebulus.…”

Nanoparticles and nanomaterials have gained a huge amount of attention in the last decade due to their unique and remarkable properties. Metallic nanoparticles like zinc oxide nanoparticles (ZnONPs) have been used very widely as plant nutrients and in wastewater treatment. Here, ZnONPs were synthesized by using onion peel and characterized by various sophisticated instruments like Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), and field emission scanning electron microscopes (FESEM). FTIR confirmed ZnONPs synthesis due to the formation of the band in the region of 400–800 cm−1, while FESEM confirmed the spherical shape of the particles whose size varies in the range of 20–80 nm. FTIR revealed several bands from 1000–1800 cm−1 which indicates the capping by the organic molecules on the ZnONPs, which came from onion peel. It also has carbonyl and hydroxyl groups, due to the organic molecules present in the Allium cepa peel waste. The average hydrodynamic size of ZnONPs was 500 nm as confirmed by DLS. The synthesized ZnONPs were then used as a plant nutrient where their effect was evaluated on the growth of Vigna radiate (mung bean) and Triticum aestivum (wheat seeds). The results revealed that the germination and seedling of mung and wheat seeds with ZnONPs were grown better than the control seed. However, seeds of mung and wheat with ZnONPs at median concentration exposure showed an enhancement in percent germination, root, and shoot length in comparison to control. Thus, the effect of ZnONPs has been proved as a nano-based nutrient source for agricultural purposes.

Calcium oxide nanoparticles (CaO NPs) have unique catalytic and biological properties; their activities are highly influenced by their morphology; as a result, these characteristics are most needed for various applications in several fields, including material science, environmental science, and medicinal science. The primary motivation for synthesizing CaO NPs using a biological method is to suppress the usage of hazardous chemicals used in making its process, which will be more cost-effective and ecologically profitable. However, due to the complexity of the biological extracts employed in chemical processes, large-scale manufacturing of nanoparticles via the green synthesis approach remains a significant problem. As a result, the production of CaO NPs utilizing Moringa oleifera plant leaves aqueous extract as an alternative biological agent for capping, stabilizing, and reducing agents due to rich phytochemical parameters in synthesis was investigated in this study. The structural characterization of the CaO NPs obtained by using UV-Vis, FTIR, XRD, and SEM-EDS indicates the presence of purity and primarily aggregated spherical nanosized material with an average size of 32.08 nm observed. The XRD study revealed that heat annealing increased the size of the crystallites, favoring monocrystalline. Finally, these findings, together with the cheap cost of synthesizing the plant-mediated CaO NPs produced, show good antimicrobial (gram-positive) activities.
