Cutting-edge research on graphite-like carbon nitride-based (g-C₃N₄) photocatalytic systems for molecular nitrogen fixation is summarized. The properties of modified g-C₃N₄ with grafted functional groups, structural defects (nitrogen or carbon vacancies), doped with nonmetals and metals, as well as g-C₃N₄-based binary and ternary composites with the participation of metals, their oxides, metalates, carbonates, hydrocarbons, and sulfides are discussed. The most promising areas of further research are outlined.
