Abstract
Abstract The bottlenecks in photocatalytic materials primarily center on light absorption capacities and rapid charge recombination. Thus, many gigantic effects have been undertaken by worldwide scientists to address the issues. In this concept, carbon‐based photocatalysts, such as graphene or graphitic carbon nitrides (g‐C 3 N 4 ), would frequently capture scientific fascination due to their distinct properties in catalytic applications. However, traditional materials would possess the drawbacks mentioned above. In the current era, nitrogen‐rich graphitic carbon nitrides (g‐C 3 N 5 ) have emerged as a promising star for photocatalytic applications due to the significant enhancements in light absorption properties, which can activate in ultraviolet, visible, and even under near‐infrared irradiations. This review will summarize the recent progress in the fabrication of g‐C 3 N 5 and the photocatalytic application of these based materials by thoroughly investigating current literature studies. Thus, updating the current trend in state‐of‐the‐art materials would motivate researchers to explore the field further.
