“…There are a wide variety of traditional chemical and physical methods for CuO NPs fabrication including electrochemical methods [26], sonochemical [27], alcohothermal [28], hydrothermal decomposition [29], precipitation [30], polyol [31], and gamma radiation [32]. To avoid serious environmental hazards and health effects of chemical synthesis methods, several reports on phyto-assisted synthesis of CuO NPs by different parts of plant extracts have been published including abutilon indicum leaf [33], Saraca indica leaves [34], Rheum palmatum L. root [35], Aglaia elaeagnoidea flower [36], Malus domestica leaf [37], and green pea [38].…”

A facile novel green methodology is presented for the synthesis of highly stable and well-dispersed copper oxide nanoparticles using aqueous wheat seed extract. Under optimal reaction conditions, the wheat seed extract-derived electron-rich biomolecules were functioned as a reducing and capping/ stabilizing agent. The ultraviolet-visible absorption peak at 300 nm was confirmed the formation of copper oxide nanoparticles. Fourier-transform infrared spectroscopy analysis determined Cu–O bonds in nanosample, indicating the active role of functional groups in the wheat seed extract in bio-reduction of Cu cations. X-ray diffraction pattern results demonstrated the monoclinic structure of highly pure biosynthesized copper oxide nanoparticles with a crystallite size of 20.76 nm. The stability of copper oxide nanoparticles was confirmed after 3 months’ storage of product with no sedimentation or suspension. Transmission electron microscopy results showed the spherical shape of nano-particle with an average size of 22 ± 1.5 nm. X-ray photo-electron spectroscopy analyses revealed only copper and oxygen elements in the sample, confirming the purity of copper oxide nanoparticles. Bio-assisted copper oxide nanoparticles demonstrated significant catalytic efficiency and reusability toward 4-nitrophenol removal by an average of 97.6% from aqueous solutions after successive 5 days’ exposure to UV irradiation.

“…These could also be applicable in biological sensing and bio-labelling [97]. Degradation activity of CuO NPs was higer than Ni@Fe 3 O 4 against organic dyes such as congo red, methylene blue and Rhodamine B [98] and also showed reduction of 4-nitrophenol [99] to treat Textile Wastewater. Aspergillus species responsible to produce aflatoxins (AFs) which is found to be carcinogenic, mutagenic etc., the adsorbent capacity of Cu-NPs for aflatoxin B1 was found to be more than Ag-NPs but less than Fe-NPs [100].…”

“…In 2017, Bordbar and co‐workers used Rheum palmatum L. root extract (Figure ) to produce of CuO NPs supported on the surface of the clinoptilolite . Recent studies on Rheum palmatum L. root extract revealed the presence of potent antioxidant phenolics . The high activity of the extract root was ascribed to the relatively antioxidant components.…”

Copper nanoparticles (NPs) are one of the most commercialized nanomaterials. From the standpoint of nanotechnology copper-based nanostructured materials have many applications in biological process, folk medicine, electronics, and industrial fields. With growing concern regarding the energy crisis and problems of chemical and physical procedures to prepare the metal nanoparticles, efforts for alternative traditional chemistry attracted particular considerations. A widespread of researches have studied on biological methods which do not generate hazardous waste and therefore, don't need the purification processes. Plants could be remarkably valuable to exploring the biogenic synthesis of metal nanoparticles. The aim of this review is to provide further insight in to connections between plant extracts and synthesis of copper NPs. The utilization of living plants for biosynthesis of metal nanoparticles (MNPs) is a cost-effective and eco-friendly procedure. To date, the obtained results demonstrated several aspects of the plant physiology and their relations to nanoparticle synthesis. This work describes the state of the art and future challenges in green synthesis of copper NPs. This review has proven recent elevation in the green synthesis of Cu NPs, CuO NPs, Cu O NPs, CuS NPs, CuAl O and immobilized copper nanoparticles on the numerous supports such as Natrolite, bentonite, perlite, ZnO, MgO, MnO , reduced graphene oxide (RGO), and Fe O by a wide range of plant extracts. Therefore, detailed description of green synthesis and stabilizing agents concerning copper nanoparticles using these green sources is presented. Also, the catalytic activities of synthesized Cu-based recyclable nanocatalysts using various plant extracts in several chemical reactions such as oxidation, reduction, hydration, cyanation, cycloaddition, and coupling reactions were consciously investigated.
