Abstract Photocatalytic nitrogen fixation has evolved as potential sustainable technique for producing ammonia in contrast to Haber‐Bosch (HB) process. In this process, semiconductor‐based materials are utilized the presence of light and water, thereby making it less energy‐intensive more eco‐friendly. However, photocatalytic have several disadvantages, including limited chemisorption activation nitrogen, low absorption, rapid charge recombination, sluggish kinetics. To overcome these issues, design catalyst tailoring active surface sites vital so that enhanced performance can be achieved. Also, there is debate about correct determination due interference by nitrogenous impurities. Taking all factors into consideration, review examines recent reports on defects modified (vacancy doping), facet‐engineered, heterojunction‐based catalysts fixation. The different quantification techniques like Nessler's reagent, indophenol method, ion chromatography (IC), etc. been discussed detail along with issues associated them. Finally, existing challenges outlook emerging technology presented. It expected will assist researchers understanding current state field effectively implementing pave way future advancements.

Photocatalytic nitrogen fixation is one of the important pathways for green and sustainable ammonia synthesis, but extremely high bonding energy N≡N triple bond makes it difficult conventional photocatalysts to directly activate hydrogenate. Given this, we covalently grafted phenanthroline unit onto graphitic carbon nitride nanosheets (CN) by simple thermal oxidation method complexed with transition metal Fe3+ ions obtain stable dispersed Fe active sites, which can significantly improve photocatalytic activity. The Fe(III)-4-P-CN photocatalyst morphology consists porous lamellar structures internally connected nanowires. special catalysts gives them excellent performance, an average NH3 yield 492.9 μmol g–1 h–1, 6.5 times higher than that pristine CN, as well better cycling stability. Comprehensive experiments density-functional theory results show more favorable CN *N2 activation, effectively lowering reaction barrier. Moreover, other byproducts (such nitrate H2O2) are also produced during process, provides a new way nitrogen-fixing achieve multifunctional applications.
