Abstract

The use of carbon-based fuels causes a significant increase in CO2 emissions, posing a serious threat to the environment. This review explores the potential application of graphitic carbon nitride (g-C3N4) in photocatalytic CO2 reduction as a strategy to mitigate global warming. The effectiveness of g-C3N4 (gCN) in this process is hindered by several factors, including rapid exciton recombination, limited solar light absorption, and a lack of active sites for conducting the reduction. To address these challenges, various amendment techniques have been executed, such as adjusting the morphology of g-C3N4, doping it with different atoms, and forming heterojunctions with other semiconductors. This review highlights the role of S-scheme heterojunctions in expanding the photocatalytic activity of g-C3N4 and emphasizes that, despite its potential as a photocatalyst for CO2 reduction, further research and innovation are essential to overcome its current limitations.
