Flash graphene: From synthesis to potential applications

The global impact of the poor waste management practices in developing countries has begun to weary the developed nations of the world. For this reason, researchers have striven to provide sustainable solutions to the waste management crisis by improving the effectiveness of the existing waste management systems and developing new methodologies for converting waste into energy and useful materials. The latest breakthrough in the conversion of waste into useful materials is the synthesis of flash graphene through flash joule heating technology. However, studies on flash graphene have remained a niche research area for a few authors, despite the unique properties and potential applications of flash graphene. Though this situation could be attributed to a number of factors, the authors believe that more researchers would be motivated to study the synthesis and applications of flash graphene if there were sufficient review articles on the subject matter. To this end, the authors have comprehensively reviewed the existing literature, with the primary objective of systematically discussing the research findings on flash graphene synthesis, characterisation and applications.
