Biosynthesis and characterization of phyto mediated zinc oxide nanoparticles: A green chemistry approach

Facile Green Synthetic Route to the Zinc Oxide (ZnONPs) Nanoparticles: Effect on Green Peach Aphid and Antibacterial Activity

“…Recently, plant extracts have been suggested as possible eco-friendly, alternative to chemicals in synthesis of nanoparticles. Different plants extracts have been reported in the open literature for green synthesis of zinc oxide nanoparticles, such as Olea europea (Awwad et al, 2014), Eichhornia crassipes leaf (Vanathi et al, 2014), Aloe barbadensis Miller leaf (Sangeetha et al, 2011), Hibiscus subdariffa leaf (Bala et al, 2015), Solanum nigrum leaf (Ramesh et al, 2015), Camelia sinesis leaf (Shah et al, 2015), Hibiscus rosa-sinensis (Devi & Gayathri, 2014), Cassia fistula plant extract (Suresh et al, 2015), Ocimum tenuiflorum leaves (Raut et al, 2015), Trifoliumpratense flower extract (Dobrucka & Dugaszewska, 2016), Mimosa Pudica leaves and coffee powder (Fatimah et al, 2016), Rambutan peel extract (Karnan & Selvakumar, 2016) Jacaranda mimosifolia flowers , Terminalia chebula fruits (Rana et al, 2016) and Azadirachia indica (Madan et al, 2016).…”

GREEN SYNTHESIS, CHARACTERIZATION AND ANTIBACTERIAL STUDIES OF CuO NANOPARTICLES FROM EICHHORNIA CRASSIPES

“…Green synthesis of nanoparticles using Eichhornia crassipes is gaining importance nowadays which may be a better alternative for its disposal by a constructive mean. 15 Green synthesis of CuO nanoparticles from the aqueous extract of Eichhornia crassipes leaves using NaOH, its characterization and its antibacterial activities against pathogenic bacteria were reported in this work. …”

Preparation, Characterization and Evaluation of Nano Zinc Oxides as Pigments

“…For example as catalysts, in paints and other construction applications (1) .By introducing the nano technology, zinc oxide gains a special attention. Zinc oxide nano sized powder have unique optical and electrical properties (1)(2)(3) ,which introduce advanced applications such as chemical and gas sensors, rubber industry to reduce vulcanization process time, cosmetic and pharmaceutical industries (4)(5)(6) . Thin films of nano sized ZnO are used in the more advanced applications such as transparent transistors (7) , solar and photovoltaic devices (8,9) , UV rays, and varistors (10,11) .…”

“…In general, zinc oxide powder is produced by three distinct processes (4,12) ; direct oxidizing zinc metal, or reduction of an ore to zinc metal followed by controlled re-oxidation, to a far lesser extent or precipitation of the oxide or carbonate from an aqueous solution followed by calcinations. Where Nano-sized zinc oxides are prepared by using different advanced methods such as, sol-gel method (5,13) , thermal deposition, spray pyrolysis and modified precipitation methods.…”

“…Also, this work extended to evaluate the produced materials as pigments according to the standard methods and in comparison with a commercial ZnO. 4 OH solution supplied by Kemika were used. All materials were used without further purification.…”
