Polymeric graphitic carbon nitride (g‐C3N4) and various carbon materials have experienced a renaissance as viable alternates in photocatalysis due to their captivating metal‐free features, favorable photoelectric properties, and economic adaptabilities. Although numerous efforts have focused on the integration of both materials with optimized photocatalytic performance in recent years, the direct parameters for this emerging enhancement are not fully summarized yet. Fully understanding the synergistic effects between g‐C3N4 and carbon materials on photocatalytic action is vital to further development of metal‐free semiconductors in future studies. Here, recent advances of carbon/g‐C3N4 hybrids on various photocatalytic applications are reviewed. The dominant governing factors by inducing carbon into g‐C3N4 photocatalysts with involving photocatalytic mechanism are highlighted. Five typical carbon‐induced enhancement effects are mainly discussed here, i.e., local electric modification, band structure tailoring, multiple charge carrier activation, chemical group functionalization, and abundant surface‐modified engineering. Photocatalytic performance of carbon‐induced g‐C3N4 photocatalysts for addressing directly both the renewable energy storage and environmental remediation is also summarized. Finally, perspectives and ongoing challenges encountered in the development of metal‐free carbon‐induced g‐C3N4 photocatalysts are presented.

碳-石墨碳氮化物杂化物用于非均相光催化
聚合石墨碳氮化物（g-C 3 N 4）和各种碳材料由于具有诱人的无金属特性，良好的光电性能和经济适应性，因此在光催化中成为可行的替代品，已开始复兴。尽管近年来已进行了许多努力，以使两种材料具有最佳的光催化性能，但这种新兴增强技术的直接参数尚未完全总结。全面了解g‐C 3 N 4与碳材料之间的协同作用对光催化作用的影响对于进一步发展无金属半导体在未来的研究中至关重要。这里，碳/ gC 3 N 4的最新进展对各种光催化应用中的杂化材料进行了综述。重点介绍了通过将碳引入g-C 3 N 4光催化剂并涉及光催化机理的主要控制因素。这里主要讨论五种典型的碳诱导增强作用，即局部电修饰，能带结构修整，多电荷载流子活化，化学基团官能化和丰富的表面修饰工程。还总结了碳诱导的g‐C 3 N 4光催化剂对直接解决可再生能源存储和环境修复的光催化性能。最后，在开发无金属碳诱导的g‐C 3时遇到的观点和持续的挑战提出了N 4种光催化剂。
