Graphitic carbon nitride/graphene-based nanomaterials for hydrogen storage

Hydrogen is a clean and renewable energy source that has the potential to replace fossil fuels in many applications. However, the storage of hydrogen is a major challenge for its widespread use. Currently, hydrogen is mainly stored in compressed gas or liquid form, which requires high pressure or low temperature conditions, making it expensive and impractical for everyday use. This chapter provides recent progress for the high hydrogen storage capacity of graphitic carbon nitride/graphene-based nanomaterials at ambient conditions, using protons as the hydrogen source instead of hydrogen gas. This has significant implications for the practical use of graphene and graphitic carbon nitride as hydrogen storage materials, as it eliminates the need for high pressure or low temperature conditions. Further research is needed to optimize the electrochemical system and improve the efficiency of hydrogen storage on graphene and graphitic carbon-based nanomaterials.
