With the rapid advancement of industrialization, dye-containing wastewater has emerged as one of the primary pollution sources in aquatic environments, posing a significant threat to ecosystems and human health. S-scheme heterojunction photocatalysis technology, known for its high efficiency and environmental compatibility, is considered a strategic solution for addressing environmental pollution challenges. In recent years, significant progress has been made in the development of S-scheme heterojunction photocatalysts based on graphitic carbon nitride (g-C3N4). However, systematic summaries and in-depth analyses of these advancements remain limited. This study provides a comprehensive review of the research progress of g-C3N4-based S-scheme heterojunction systems in the field of photocatalytic dye degradation. It elaborates on the fundamental concepts, operational mechanisms, and representative applications of these systems while exploring the latest advancements in synthesis strategies, catalytic performance optimization, and the underlying mechanisms. Finally, this review discusses the existing challenges and future prospects of g-C3N4-based S-scheme heterojunction photocatalytic materials, aiming to offer valuable insights and guidance for further research in this area.
