This paper reviews the resurgence of polymeric graphitic carbon nitride (g-C3N4) and various carbon materials as viable alternates in photocatalysis. It highlights the importance of understanding the synergistic effects between g-C3N4 and carbon materials in catalytic action and discusses the five typical carbon-induced enhancement effects. Furthermore, it summarizes the photocatalytic performance of carbon-induced g-C3N4 photocatalysts for renewable energy storage and environmental remediation, and presents perspectives and ongoing challenges in the development of metal-free carbon-induced g-C3N4 photocatalysts.
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.
