Green synthesis of CuO nanoparticles by aqueous extract of Anthemis nobilis flowers and their catalytic activity for the A3 coupling reaction

A Review on Recent Advances in the Application of Nanocatalysts in A3 Coupling Reactions

“…Recently Nasrollahzadeh and co‐workers reported the preparation of the CuO NPs via a simple, effective and green method by using Anthemis nobilis flowers extract as a reducing and stabilizing agent . The size and morphology of the CuO NPs was analyzed by SEM images as displays in Figure .…”

“…It is important to stress that despite huge advancements of the reported works in the literature, another important challenges in the A 3 coupling reactions is nature of solvent and kind of the catalyst. A number of nanocatalysts, including copper, silver, gold, nickel, magnetic nanocatalysts and Co 3 O 4 , ZnS and nanopowder zinc titanate were successfully applied for A 3 coupling reactions with yields ranging from good to excellent in appropriate times in organic solvents or aqueous medium . The authors ascribed high catalytic activity of nanocatalysts to the particles size.…”

Synthesis paradigm and applications of silver nanoparticles (AgNPs), a review

“…Nowadays, metal based nanoparticles are synthesized for numerous applications from different plant parts such as leaves, roots, flower, seeds etc. For instance, Cu/Fe 3 O 4 nanoparticles from Silybum marianum L. Seed extract [12], Cu/reduced graphene oxide/Fe 3 O 4 nanocomposite from Euphorbia wallichii leaf extract [13], Gold nanoparticles (AuNPs) from Anthemis xylopoda flower aqueous extract [14], Palladium nanoparticles from the Hippophae rhamnoides linen leaf extract [15], Pd/Fe 3 O 4 nanoparticles from Euphorbia condylocarpa M. bieb root extract [16], Palladium nanoparticles (PdNPs) from Sour Cherry tree Gum [10], Copper nanoparticles supported on bentonite (bentonite/CuNPs) from Thymus vulgaris L. leaf extract [17], Pd nanoparticles supported on graphene oxide from barberry fruit extract [18], Natrolite zeolite/Pd nanocomposite using Piper longum fruits extract [19], Cu/reduced graphene oxide (RGO-Fe 3 O 4 ) using nanocomposite Berberis vulgaris fruit extract [20], CuO nanoparticles by aqueous extract of Anthemis nobilis flowers [21], AuNPs by Anthemis xylopoda flowers [22], CuNPs using Ginkgo biloba L. leaf extract [23], PdNPs using Euphorbia thymifolia L. leaf extract [24], CuNPs using Euphorbia esula L leaves extract [25], PdNPs using Hippophae rhamnoides linn leaf extract [15], Pd/Fe 3 O 4 nanoparticles using Euphorbia condylocarpa M. bieb root extract [26], Au/Pd bimetallic nanoparticles from Euphorbia condylocarpa M. bieb [27], biosynthesis of AgNPs for application Ag/bone nanocomposite Myrica gale L. extract [28], Ag/RGO/Fe 3 O 4 using Lotus garcinii leaf extract for nano-catalyst [29], AgNPs using Gongronema latifolium leaf extract [30], green synthesis of PdNPs using Salvia hydrangea extract for catalyitic reduction of dyes [31], green synthesis of AgNPs supported on waste peach kernel shell using Achillea millefolium L. extract [32], synthesis of Ag/ Fe3O4 nanocomposite using Euphorbia peplus Linn leaf extract [33], and synthesis of Pd/perlite nanocomposite using Euphorbia neriifolia L. leaf extract [34].…”

A Green Strategy to Synthesize Environment Friendly Metal Oxide Nanoparticles for Potential Applications – A Review

“…Both Anthemis nobilis flowers and Gundelia tournefortii belong to Asteraceae family. Both have good reducing and stabilizing capabilities [45,46]. Tinospora cordifolia belongs to Menispermaceae family.…”

“…Then, the color change was observed during the heating process due to excitation of surface plasmon resonance which indicates the formation of CuO NPs. The obtained solution of NPs was centrifuged at 6500 rpm for 30 minutes and precipitation was then air-dried for 24 h at room temperature [45]. Green tea leaf powder was added to distilled water and kept under a magnetic stirrer for 2 hrs at 80°C.…”
