Graphitic Carbon Nitride/Graphene Hybrids as New Active Materials for Energy Conversion and Storage

Energy conversion and storage devices play an important role in industry and society with the rapid growth of energy consumption. Developing a highly efficient, environmentally friendly device mainly depends on improvements in high-performance electrode materials or catalysts. Recently, graphitic carbon nitride/graphene (g-C3N4/graphene) hybrids have drawn considerable attention and shown great potential as active materials in the field of energy conversion and storage due to their unique and tunable nanostructure, high nitrogen content, and conductivity. This review focuses on the recent significant advances in the fabrication and application of g-C3N4/graphene hybrids as electro- or photocatalysts and electrode materials. Synthetic strategies and applications for photo- or electro-related devices are presented, accompanied with a discussion of the challenges and research directions for the future development of g-C3N4/graphene hybrids.
