Graphene Oxide with Controllable Reduction Level: An Approach to Space Applications

The use of graphene oxide has attracted considerable attention in various fields due to its exceptional properties. In this paper, we present an approach focused on the controllable reduction level of graphene oxide and its potential applicability. This controllability not only affects its electrical and optical properties, but also expands the possibilities of its use in specific space applications. This paper investigates the synthesis of graphene oxide using a modified Hummers method. X-ray diffraction patterns of the obtained materials have been analyzed according to the Rietveld method. The average size of graphene oxide particles has been determined. The study has examined the dependence of the optical properties of a colloidal solution of graphene oxide on the pH of the medium. The results obtained offer insights applicable to advancing techniques for the targeted modification of graphene oxide, especially as an acceptor for photovoltaic solar cells. The potential implications of this research contribute to the evolving materials for energy harvesting and conversion applications.
