摘要
Single-atom photocatalysts,due to their high catalysis activity,selectivity and stability,become a hotspot in the field of photocatalysis.Graphitic carbon nitride(g-C3N4)is known as both a good support for single atoms and a star photocatalyst.Developing g-C3N4-based single-atom photocatalysts exhibits great potential in improving the photocatalytic performance.In this review,we summarize the recent progress in g-C3N4-based single-atom photocatalysts,mainly including preparation strategies,characterizations,and their photocatalytic applications.The significant roles of single atoms and catalysis mechanism in g-C3N4-based single-atom photocatalysts are analyzed.At last,the challenges and perspectives for exploring high-efficient g-C3N4-based single-atom photocatalysts are presented.
