Abstract: Carbon nitride (g-C3N4) as a polymeric semiconductor is extensively investigated as a potential next-generation material in the field of catalysis, optoelectronics, energy conversion and storage, due to its high physicochemical and thermal stability as well as suitable bandgap 2.6-2.7 eV, as a low-cost material. However, some major issues, like low surface area, serious irretrievable capacity forfeiture and deprived electrical conductivity, restrict its potential application in energy storage applications. However, several methods of material structures properties to improve its activity with unique morphological characteristics are not sufficiently summarized in the literature yet. Therefore, the present review article is intended to collect the data of key methods to prepare g-C3N4 with different morphological characteristics in detail. Moreover, this review systematically discusses the use of g-C3N4 with the latest information for energy conversion and storage applications, especially photocatalytic hydrogen production (PHP), photocatalytic carbon reduction (PCR), different batteries, supercapacitors (SCs), etc. Finally, key challenges and prospects to prepare advanced g-C3N4 for energy conversion and storage field with its environmental consequences are presented in detail.
