Recent Development of Nanoparticle by Green-Conventional Methods and Applications for Corrosion and Fuel Cells

Nowadays, numerous researches have focused on the field of green nanotechnology worldwide and their various applications. The main reason is the environmental and biologically safe applications of nanoparticles. Until now, various nanoparticles have been fabricated and tested for different purposes, such as energy conversion, storage, and corrosion prevention. However, conventional nanoparticle production, like physical or chemical methods, caused undesirable adverse effects on humans and the environment. Various biological materials have numerous advantages, such as environmentally friendly, non-toxic, and abundant availability. Thanks to these advantages, green synthesis methods may have a wider field of use in the future compared to traditional methods. Furthermore, the use of green materials provides significant advantages such as less usage of energy, economic and natural resources. Recently, considerable efforts have been carried out to develop novel green nanoparticles using various biological sources and methods such as the hydrothermal method, microwave-assisted method, ultra-sonication assisted method and mechano-mixing methods. In this review, we discuss the main properties of green and recent nanoparticles synthesized by green and conventional methods for using in corrosion preventions and fuel cells. In the paper, the fundamental sources of green nanoparticles and the fabrication process are addressed. The main reasons for the corrosion and the prevention of corrosion are explained. Also, the current analysis methods used to characterize the morphological and chemical properties of the recently synthesized nanoparticles are explained.
