This review systematically analyzes and summarizes the recent advances in graphitic carbon nitride (g-C3N4)-based composites, including preparation, characterization, modification, and environmental application. The focus is on the modification mechanisms and environmental applications. Concluding remarks and perspectives for further study are provided.
Graphitic carbon nitride (g-C3N4)-based materials have received extensive attention due to their unique characteristics, such as optical properties, high chemical stability, facile synthesis. In this review, the recent advances in g-C3N4 composites were systematically analyzed and summarized, including preparation, characterization, modification, and environmental application, particularly focusing on the modification mechanisms and environmental applications. Firstly, the preparation methods of g-C3N4 on the basis of pyrolysis were introduced. Then, the characterization techniques for determining the structure of g-C3N4 and the corresponding specific parameters, such as X diffraction angle and C-N binding energy were briefly introduced. Thirdly, various modification methods of g-C3N4 were discussed. Fourthly, the diverse applications of g-C3N4 in the field of environmental remediation were summarized in detail, such as photo-catalyst, Fenton-like catalyst, adsorbent, and disinfectant. Finally, the concluding remarks and perspectives were made for further study. This review will deepen the understanding of the state of the art of g-C3N4, including the preparation, characterization, modification and environmental application. (C)2021 Elsevier B.V.
