About this Research Topic
Graphene and functionalized graphene-based nanocomposites with metal, metal oxide, chalcogenides, quantum dots, etc. have unique chemical, optical, electronic, and mechanical properties that can form the foundation for the development of a wide range of nanostructures, and can be used in catalysis and photocatalysis for energy- and environment-related applications.
The synthesis of such nanomaterials, as well as their hybrid nanomaterials, has been broadened several-fold, and continuous efforts are being made to integrate it into various energy, environmental, electronic, and biomedical applications; these nanomaterials possess excellent stability, mechanical strength, electrical and thermal conductivity, and optical properties. In order to achieve sustainable and affordable graphene and functionalized graphene-based technology, nanocomposites are of great importance for both scientific research and industrial applications.
Hence, understanding the structural (nano- or micro-structure), surface, and physicochemical properties of graphene-based nanostructures is important for achieving the required efficiency, stability, reusability, and sustainability of the nanocomposites in various technological applications. Graphene-based nanocomposites or hybrid nanostructured systems can be developed in various ways wherein their characteristic properties can be fine-tuned depending on their structure, functional groups, band gap, size, shape, and surface properties (such as level of disorder, surface energy, functional groups, and the dimensions of the flakes). The structural properties of graphene and graphene-based nanocomposites can be determined using the combination of characterization techniques such as XRD, UV-vis DRS, PL, electro-chemical properties, Raman spectroscopy, AFM, SEM, and TEM. Structural and electrochemical characteristics such as electronic structure, as well as band structure of the composites and surface-modified graphene, will be helpful to fully understand the electronic, optical, thermal, and mechanical properties of graphene and graphene based-nanocomposites.
