Graphitic Carbon Nitride Based Materials Towards Photoproduction of H2O2

Abstract 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.
