“…As displayed visually in Figure 27, both MB and CR became colorless gradually after the addition of biogenic CuO in less than 2 h. They further pragmatically concluded that the decolorization, which is core visual evidence of degradation, is a function of exposure duration of the pollutant to green nanocatalyst and irradiation. [176] A very similar excellent result has been obtained by other research teams [140,156,160,170] using green CuO NPs biofabricated by employing Canthium coromandelicum leaf extract, Cardiospermum halicacabum plant extract, green tea extract, and Ocimum tenuiflorum leaf extract respectively.…”

The present scenario of water insecurity (poor availability and accessibility to clean and healthy water when needed) denotes the preponderance of environmental damage caused by effluents or waste runoff from industries, such as the dye and textile industries. The polluted waters have led to terrible and sonorous negative impacts on the ecosystem and econetworking, thus, urging for a sustainably suitable substitute to tackle and annul the noxious environmental constraint posse by the hazardous dye effluent. Several chemical and physical methods for treating dye effluent are now in use, but they are time‐consuming, expensive, and inefficient. Interestingly, nanoparticles have egressed as a superior answer for efficient dye removal and degradation, because of their chemical reactivity and exceptional surface characteristics. As a result, the use of metal nanomaterials in the treatment of dye runoffs has been thoroughly investigated. The study used major scientific databases such as SciFinder, Scopus, PubMed, Google Scholar, and Science Direct to conduct a comprehensive review of publicly available literature. Degradation, dye effluent, green metal nanoparticles, and water pollution were the keywords used to find scholarly papers. Efforts were made to figure out and explain the mechanism of dye effluent degradation, how long the degradation will take and how effective the use of plant biosynthesized metal nanoparticles for dye removal is. In addition, the role of bimetallic nanoparticles has also been investigated with remarkable feat from literature. The current level of knowledge about the mechanism and the use of plant biogenic metal nanoparticles in common dye effluent treatment is summarized in this paper.

“…Many researchers have been interested in using copper oxide nanoparticles as agents with antimicrobial activity against Gram-positive and Gram-negative bacteria as well as anti-fungal activity. In a previous study, Selvam et al found that copper oxide nanoparticles in Canthium coromandelicum leaves degraded MB by 91% in 180 min [ 51 ]. The biosynthesized CuO-NPs using Calotropis procera leaf extract have recently attracted antibacterial and antifungal activity [ 52 ].…”

“…The peaks patterns as shown in Figure 5, revealed peaks position at 31.24°(110), 35.04°(002), 36.7.6°(111), and 50.12°(200), which clearly matches with the peaks of the JCPDS card number 89–2529. [ 54,56 ] This result clearly indicates the green synthesized CuONPs are in crystalline nature and crystallized in the structure of FCC (face‐centered cubic). Peak observed at 17 and 27, which indicates that copper was oxidized and converted into copper oxide thus these spectra confirm the formation of CuONPs in the reaction mixture the peaks match with the JCPD (File No.089‐2838), which further proves the formation of crystals of CuONPs.…”

An eco‐friendly green route for synthesis copper oxide nanoparticles (CuONPs) by Prunella vulgaris flower aqueous extract is reported. The synthesized copper oxide nanoparticles are characterized in terms crystalline nature, morphology, structural, and antibacterial activity with UV‐vis, SEM, DLS, FTIR analysis tools. The synthesized CuONPs are well crystalline in nature with particle shape spherical and average particle size in the range 41–76 nm. The antimicrobial activity of CuONPs, determined by disk diffusion method against S. aureus and K. pneumoniae, demonstrates a significant inhibitory activity against S. aureus followed by K. pneumoniae. In view of the promising activity, CuONPs can be used as an antibacterial agent. The possible mechanisms of antimicrobial activity of CuONPs should be further investigated.
