Graphitic carbon nitride decorated with C–N compounds broken by s-triazine unit as homojunction for photocatalytic H2 evolution

A new homojunction is developed by in situ decorating g-C 3 N 4 (CN) nanosheets with a C–N compound broken by s -triazine units (BST). The BST fragments rapidly transfer photogenerated electrons from the CN conduction band to generate hydrogen.
