ZnO nanohemispheres are successfully synthesized via thermal decomposition approach using [bis(2-hydroxy-1-naphthaldehydato)zinc(II)] complex, as precursor. The final ZnO nanoparticles werecharacterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electronmicroscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, and photoluminescence (PL)spectroscopy. Furthermore, the same solid phase thermal treatment is preformed and the morphology iscompared with the obtained ZnO nanohemispheres.

The strategy for design of new nanometals was developed due to their wide applications in many fields. One of the most important nanometals is silver nanoparticles (AgNPs) because of their extensive applications in biotechnologyand biomedical fields. AgNPs were usually synthesized by using chemical and physical methods. In thechemical methods, various toxic chemicals are used, which are harmful to the health of living organisms. Therefore,the AgNPs were synthesized by using biological methods based on green chemistry for reducing the toxic chemicals. There are various resources for green synthesis of AgNPs, such as bacteria, fungi, enzyme and plant extracts. The greensynthesis of AgNPs involves three main steps: the selection of the solvent medium, the selection of environmentallyreducing agents, and the selection of non-toxic substances for the stability of AgNPs. The biosynthesis of AgNPs usingplant extracts is more favorable than other biological methods because of removing the elaborate process of maintainingcell cultures. It can be also suitably scaled up for large scale production of AgNPs. This review focuses on green synthesisof AgNPs using various plant extracts.
