In the current world situation, population and industrial growth have become major problems for energy and environmental concerns. Extremely noxious pollutants such as heavy metal ions, dyes, antibiotics, phenols, and pesticides in water are the main causes behind deprived water quality leading to inadequate access to clean water. In this connection, graphite carbon nitride (GCN or g-CN) a nonmetallic polymeric material has been utilized extensively as a visible-light-responsive photocatalyst for a variety of environmental applications. This review focuses on recent developments in the design and photocatalytic applications of metal-doped GCN-based nanomaterials in CO photoreduction, water splitting toward hydrogen production, bacterial disinfection, and organic pollutant degradation. Additionally, this review discusses various methods of using GCN-based materials to optimize dye sensitization, metal deposition, ion doping, and their environmental applications.
在当前的世界形势下，人口和工业增长已成为能源和环境问题的主要因素。水中的重金属离子、染料、抗生素、酚类和农药等剧毒污染物是水质恶化导致清洁水供应不足的主要原因。在这方面，石墨氮化碳（GCN或g-CN）这种非金属聚合物材料已被广泛用作可见光响应光催化剂，用于各种环境应用。本综述重点关注金属掺杂的基于GCN的纳米材料在CO光还原、水分解制氢、细菌消毒和有机污染物降解方面的设计和光催化应用的最新进展。此外，本综述还讨论了使用基于GCN的材料来优化染料敏化、金属沉积、离子掺杂及其环境应用的各种方法。
