Pure ZnO particles, doped and co‐doped with Cu2+ and Mg2+ ions were obtained by the simple sonochemical method. The wurtzite hexagonal structure was confirmed by X‐ray diffraction (XRD) patterns. The images obtained by field emission scanning electron microscopy (FE‐SEM) showed irregular and more agglomerated particles with the increase of Cu2+ and Mg2+ ions concentration in the ZnO lattice, with the average diameter of particles in the range of 57.23‐170.77 nm. The photocatalytic activity was investigated by decolorizing the methylene blue (MB) dye under UVC light irradiation which indicates that 1% Mg‐doped ZnO particles have better photocatalytic activity than the other samples, and presented the highest kinetic constant value. The co‐doped samples showed a reduced global surface area which did not favor the good photocatalytic performance. The sacrificial agents showed that OH· radicals are the main species involved in the photocatalytic activity of this system and defects generated in the ZnO lattice promoted photoluminescent emission in the red and green regions.This article is protected by copyright.

Nanotechnology is a fast-expanding area with a wide range of applications in science, engineering, health, pharmacy, and other fields. Among many techniques that are employed toward the production of nanoparticles, synthesis using green technologies is the simplest and environment friendly. Nanoparticles produced from plant extracts have become a very popular subject of study in recent decades due to their diverse advantages such as low-cost synthesis, product stability, and ecofriendly protocols. These merits have prompted the development of nanoparticles from a variety of sources, including bacteria, fungi, algae, proteins, enzymes, etc., allowing for large-scale production with minimal contamination. However, nanoparticles obtained from plant extracts and phytochemicals exhibit greater reduction and stabilization and hence have proven the diversity of properties, like catalyst/photocatalyst, magnetic, antibacterial, cytotoxicity, circulating tumor deoxy ribo nucleic acid (CT-DNA) binding, gas sensing, etc. In the current scenario, nanoparticles can also play a critical role in cleaning wastewater and making it viable for a variety of operations. Nano-sized photocatalysts have a great scope toward the removal of large pollutants like organic dyes, heavy metals, and pesticides in an eco-friendly and sustainable manner from industrial effluents. Thus, in this review article, we discuss the synthesis of several metal nanoparticles using diverse plant extracts, as well as their characterization via techniques like UV–vis (ultraviolet–visible), XRD (X-ray diffraction), SEM (scanning electron microscopy), TEM (transmission electron microscopy), FTIR (Fourier transform infrared spectroscopy), etc., and catalytic activity on various hazardous systems.

Nanotechnology is widely used by researchers due to its high surface volume ratio. It is nowadays employed in wastewater treatment due to its high efficiency. Metallic nanoparticles are used as it shows anti-microbial property and catalytic property. In the present study silver nanoparticle is used for treating the polluted water. Its characterisation is done using UV-Visible spectroscopy, FTIR (Fourier Transform Infrared Spectroscopy). The confirmation for the formation of the nanoparticle is done using the UV-Visible spectroscopy and functional group confirmation is done using the FTIR. In FTIR the peaks are observed at 3311.481 cm− 1 and 2402.918 cm− 1 corresponding to O-H Stretching and N-H Stretching. The peak at 1765.336 cm− 1 and 1358.396 cm− 1 represents the C-H Bending, and O-H Bending for the synthesised silver nanoparticle. This treated water can be further used for agricultural and domestic purposes.
