“…Fe 3 O 4 /g-C 3 N 4 was deposited on Ni foam, and Fe 3 O 4 /edge-functionalized- g -C 3 N 4 /NF nanocomposite electrodes were created to be investigated as binder-free supercapacitors. Based on the results, the electrodes obtained a specific capacitance of 197.2 mAh g –1 at 0.5 A g –1 , and cycle lives of 96.1% and 88.5% were obtained at 0.5 and 3 A g –1 , respectively, for 4000 cycles, confirming the synergetic effect in the structure . Mesoporous 3D Zn–Ni–Co–S nanowire-like arrays were grown on Ni foam for use as electrode supercapacitors and demonstrated a capacity of 418.2 mAh g –1 at a current density 4.6 mA cm –2 .…”

As a group of large-surface-area nonmetal materials, polymeric carbon nitride (C x N y ) and its hybrid structures are nowadays of ever-increasing interest for use in energy devices involved in energy conversion and storage, offering low expenses and facile production processes. With the growing requirement for clean and renewable energy generation and storage systems, progress in the replacement of expensive noble-metal catalysts with C x N y -based materials as efficient electrocatalysts has expanded considerably, and the demand for these materials has increased. The modified C x N y architectures are beneficial to electrocatalytic applications, improving their moderate electrical conductivities and capacity loss. The present review strives to highlight the recent advances in the research on the aforementioned identities of C x N y -derived materials and their structurally modified polymorphs. This review also discusses the use of C x N y -based materials in fuel cells, metal–air batteries, water splitting cells, and supercapacitor applications. Herein, we deal with electrocatalytic oxidation and reduction reactions such as hydrogen evolution, oxygen evolution, oxygen reduction, CO2 reduction, nitrogen reduction, etc. Each device has been studied for a clearer understanding of the patent applications, and the relevant experiments are reviewed separately. Additionally, the role of C x N y -derived materials in some general redox reactions capable of being exploited in any of the relevant devices is included.
