“…The co-precipitation method is the simultaneous precipitation of several compounds from a solution. It is the most practical method for the preparation of nanoparticles, in which a metal precipitates as a hydroxide from a salt precursor in the presence of a base in a solvent [ 61 ]. The synthesis of Al 2 O 3 NPs and CuONPs was conducted using Sage plant extract.…”

In the present work, Copper (Cu) doped zinc oxide (ZnO) nanoparticles were prepared using a simple and cost-effective co-precipitation process. The objectives of the proposed work are to identify the cause of Cu dopant on the crystalline structure, morphology, optical characteristics of ZnO nanoparticles for photocatalytic as well as photosensing applications. X-ray diffraction (XRD) and Field emission scanning electron microscope (FESEM) examinations were used to identify the crystal structure and morphology of the prepared samples. The crystallite size of the undoped ZnO sample was 44 nm, which gets reduced to 36 nm with 5% Cu-doping. Using diffuse reflectance spectroscopy (DRS), the band gap of prepared samples of undoped to 5wt% Cu doped ZnO was calculated, and it was found to be reduced from 3.31 to 3.26 eV. Photoluminescence (PL) spectra show a decrease in luminous intensity which is in line with the photocatalytic behavior. 5 wt% Cu doped ZnO sample displayed maximum degradation efficiency of 85% in 75 minutes and degradation rate of 0.02 min-1. Additionally, photo-sensing studies of the 5 wt. % Cu doped ZnO sample showed higher responsivity (R), detectivity (D*) and external quantum efficiency (EQE) values of 1.93  10-1 AW-1, 1.09  1011 Jones and 45 % respectively. The rise and fall time of 5 wt % Cu doped ZnO photodetector is in the order of 0.3 and 0.5 s.

This review portrays a comparison between green protocols and conventional nanoparticle (NP) synthesis strategies, highlighting each method's advantages and limitations. Various top‐down and bottom‐up methods in NP synthesis are described in detail. The green chemistry principles are emphasized for designing safe processes for nanomaterial synthesis. Among the green biogenic sources plant extracts, vitamins, enzymes, polysaccharides, fungi (Molds and mushrooms), bacteria, yeast, algae, and lichens are discussed. Limitations in the reproducibility of green protocols in terms of availability of raw material, variation in synthetic protocol, and selection of material due to geographical differences are elaborated. Finally, a conclusion is drawn utilizing green chemical principles, & a circular economy strategy to minimize waste generation, offering a promising framework for the synthesis of NPs emphasizing sustainability.
