Abstract Porous graphitic carbon nitride (g-C 3 N 4 ) was successfully synthesized by a simple bacterial etching method. Compared with bulk g-C 3 N 4 , the specific surface area of the porous g-C 3 N 4 increased from 14.48 to 75.22 m 2 /g, and its photocatalytic activity was significantly enhanced by a factor of 2.49 for photocatalytic H 2 evolution. The enhancement of photocatalytic activity is attributed to the enlarged specific surface area, remarkably narrowed band gap (2.28 eV) and fast electron transportation benefit from the porous structure.

细菌驱动的石墨氮化碳孔结构调节用于增强可见光照射下的 H2 评价

摘要 通过简单的细菌蚀刻法成功合成了多孔石墨氮化碳(gC 3 N 4 )。与本体gC 3 N 4 相比，多孔gC 3 N 4 的比表面积从14.48增加到75.22 m 2 /g，其光催化活性显着提高了2.49倍，用于光催化析氢。光催化活性的增强归因于比表面积增大、带隙显着变窄（2.28 eV）和多孔结构带来的快速电子传输。
