The favorable positions of the conduction and valence bands of RF theoretically enable RF application in photocatalytic nitrogen fixation. Nevertheless, the limited solubility of nitrogen in water results in diminishing the effectiveness of photocatalytic nitrogen fixation. Herein, we present a method to coat RF nanospheres with an ionic liquid (RF@IL) exhibiting significant nitrogen enrichment capacity to develop a novel organic semiconductor material featuring a core–shell configuration. The abundant hydroxyl functional groups on the surface of RF nanospheres facilitate the coating of imidazolium ionic liquids, affording a nitrogen-rich thin film for the RF nanospheres and segregate the sites of nitrogen reduction and water oxidation, minimizing the recombination of photogenerated carriers and thereby enhancing the efficacy of the photocatalytic nitrogen fixation reaction. RF@IL facilitated photocatalytic nitrogen fixation, yielding 58.7 µmol g<small>⁻¹</small> of ammonia in 2 hours, which is 1.80 times greater than the blank RF output of 32.6 µmol g<small>⁻¹</small>. Remarkably, after five testing cycles, RF@IL retains substantial photocatalytic ammonia synthesis activity, underscoring the considerable influence of ionic liquids on photocatalytic processes.
