“…Due to BN‐caused electron‐enriched environments on the interfaces, the photoexcited holes would move from g‐C 3 N 4 to BN, defeating the charge recombination phenomenon and thus enhancing the catalytic outcomes [228] . In contrast, if BN was replaced by graphene or other organic semiconductors, a different circumstance was observed with the electrons transferring from g‐C 3 N 4 to the second components [230,277] . In addition, heterojunction photocatalysts with a two‐channel reaction pathway's mechanism could open a promising way to increase H 2 O 2 production.…”

Hydrogen peroxide (H 2 O 2 ) can be considered as one of the world's indispensable chemicals. However, the synthetic process can prompt several severe environmental and human health issues. However, solar H 2 O 2 production may provide opportunities to mitigate such issues. Graphitic carbon nitride (g-C 3 N 4 ) has emerged as one promising material for photocatalytic applications due to its unique properties. Although tremendous efforts in engineering g-C 3 N 4 have been proposed to improve catalytic results, the materials obtained still have some issues.Additionally, the mechanisms behind the production of H 2 O 2 by using such materials are not yet fully understood. Herein, we conducted a literature survey reviewing the production of H 2 O 2 using g-C 3 N 4 -based materials. The essential aspects of and current challenges in photocatalytic H 2 O 2 generation are discussed, which may provide insight for researchers to overcome barriers and develop sustainable methods for H 2 O 2 production.

“…The photodegradation of atenolol by the composites under visible light irradiation is 4.98 times higher than that of TiO 2 . John H. et al 51 mediated the amidation reaction of NTCDA with CN by ultrasound, which increased the rate of H 2 O 2 production by 410% compared to using pure CN samples. Jason A. et al 48,52 used 5-aminoterephthalic acid condensed with NTCDA to synthesize H 4 BIPA-TC, which further reacted with Cu and Zn plasma to prepare a variety of MOF materials with photocatalytic activity.…”

Graphitic carbon nitride (g‐C3N4) assisted photocatalytic production of hydrogen peroxide (H2O2 has already attracted the interest of many researchers due to its environmental sustainability. Nevertheless, the inherent drawbacks of g‐C3N4 limit its progress. Metal‐free modification strategies, including nanostructure design, defect introduction, doping, and heterojunction construction, have been developed to improve the efficiency of g‐C3N4 photocatalytic H2O2 production. Compared to metal modification, metal‐free strategies avoid the use of precious metals and the leaching of heavy metal ions, which have the advantages of good stability and environmental friendliness. However, a comprehensive review of H2O2 production from g‐C3N4 modified by metal‐free strategies is still lacking. This review first recaps the mechanism of photocatalytic H2O2 production by g‐C3N4, including photoexcitation, carrier separation and redox reactions. Then, the perspective advances in metal‐free modified g‐C3N4 photocatalysts are presented, with the special focus on the kernel connection between different strategies and mechanism based on the pivotal stages of H2O2 production. Subsequently, recent applications of g‐C3N4‐based photocatalysts for in situ generated H2O2, mainly including water purification and organic synthesis, are briefly discussed. Finally, the prospects of g‐C3N4‐based photocatalysts are envisioned with the hope that it will have “something to do” in the field of H2O2 production.
