Synthesis of ZnO micro-flowers assisted by a plant-mediated strategy

Abstract

BACKGROUND: The synthesis and application of novel zinc micro/nanostructures are of increasing importance in modern nanotechnology.

Plant‐Mediated Synthesis of Zinc Oxide Supported Nickel‐Palladium Alloy Catalyst for the Selective Hydrogenation of 1,3‐Butadiene

“…Cinnamomum camphora leaves (C. Camphora) , as used in our previous work, were obtained from Xiamen Peony Fragrance Co Ltd, washed several times with deionized (DI) water, dried, and crushed into fine powder. Zn(NO 3 ) 2 ⋅6 H 2 O, Ni (NO 3 ) 2 ⋅6 H 2 O, and ascorbic acid (AA) were purchased from Sangon Biotech (Shanghai) Co., Ltd. Pd(NO 3 ) 2 and all other commercial supports (P25 TiO 2 , referred to as TiO 2 in this work, and SiO 2 ) were obtained from Sinopharm Chemical Reagent Co. Ltd. and used as received without purification.…”

“…The ZnO and CuO supports used were prepared by a similar method to that used in our previous studies with minor adjustments . Typically, Zn(NO 3 ) 2 ⋅6 H 2 O (30 mL, 0.2 mol L −1 ) and Cu(NO 3 ) 2 ⋅3 H 2 O (30 mL, 0.1 mol L −1 ) solutions were added to C. camphora leaf extract (10 and 20 mL, respectively) in a 150 mL round‐bottomed flask and kept at RT to age for 1 h. The respective mixtures were dried in the oven at 80 °C for 10 h and then annealed at 450 °C 4 h. The obtained metal oxides were milled by using a pestle and mortar, then sieved through a 50 mm mesh, and stored for further use.…”

Facile In Situ Synthesis of ZnO Flower-like Hierarchical Nanostructures by the Microwave Irradiation Method for Multifunctional Textile Coatings

“…Biological methods (using microorganisms and plant materials) have gradually been established as simpler, more economical, and greener methods to synthesize flower-like ZnO nanoparticles, with the potential to replace the conventional methods. Moreover, the plant-assisted routes possess bioreducing and/or bio-template components such as reducing sugars, flavonoids, and proteins [37], which allow control of the particle's size and morphologies. This should be very useful because the particle morphology can be tuned according to its final application.…”

Green synthesis of ZnO hierarchical microstructures by Cordia myxa and their antibacterial activity

“…So far, great deal of effort has been devoted towards exploring the green synthesis routes which is an efficient alternative to chemical and physical methods. The green synthesis of bioactive ZnO nano/micro-structures from various plant resources and their antibacterial, antifungal and photocatalytic activities have been documented by many researchers (Lakshmeesha et al, 2014, Tripathi et al, 2014, Yuvakkumar et al, 2014, Kavyashree et al, 2015, Odoom-Wubah et al, 2016, Udayabhanu et al, 2016).…”
