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.
