Exploring the production and storage of hydrogen energy using graphitic carbon nitride (g-C3N4)

The generation of energy using fossil fuels is not environmentally friendly and therefore causes climate change issues. Hence, exploration of avenues for the production of clean and efficient energy is on the rise. A nonmetal- based semiconductor material called graphitic carbon nitride (g-C3N4 3 N 4 or g-CN) is currently gaining tractions because of exceptional and interesting characteristics such as increased stability (chemical and thermal), unique bandgap energy and valence band, effective conductivity, and cost-effectiveness. This review work has thrown more light on graphitic carbon nitride in relation to hydrogen energy production and storage while taking into consideration the background, synthetic routes and optimisation of this non-metallic semiconductor. Furthermore, the work explored a number of studies on applications, hydrogen energy storage mechanisms, modelling, drawbacks and objective perspectives as it relates to efficient hydrogen energy production and storage. The efficiency, sustainability and commercialization become the driving force for future improvement in this technology.
