Synthesis of Graphene Nanomaterials for Energy Storage Applications

Abstract

In a recent trend, nanotechnology is an interdisciplinary engineering field that emphasizes nanoparticles with multidimensional properties. Nanoparticles are attracting interest owing to their enhanced physiochemical and biological characteristic feature at nanoscale from 1 to 100 nm. Due to the development of large industrial fields, there is a significant shortage of energy usage. Overcoming this energy crisis with viable technologies is therefore essential to protect ecosystems and the environment. Nanotechnology plays a central role in energy storage devices. Therefore, the functionalization of nanomaterials with natural materials serves as an environmentally friendly and safe technology and provides a versatile platform. Graphene oxide nanomaterials and their composites have garnered greater intention owing to attractive physicochemical and enhanced biological properties and are widely used in various fields. However, metal nanoparticles tend to aggregate and grow spontaneously, which tends to lower the surface energy, limiting the reaction efficiency and stability of the nanoparticles. The very high cost of metal nanoparticles also prevents their further use. Therefore, the design of a new generation of metal oxide nanomaterials with different properties that offer synergistic multifunctional efficiencies for different applications has been adopted. Therefore, in the field of nanomaterials, keen interest has been endowed to the synthesis of graphene oxide nanosheets using synthetic protocol that have myriad application in energy storage devices.
