Chenglu Zhu et al.

Summary: The incorporation of 2-aminobenzothiazole (ABT) into the g-C3N4 framework led to the synthesis of a series of D-A structured photocatalysts with improved performance. The enhanced photocatalytic hydrogen evolution was attributed to the broadened visible light absorption range and accelerated charge carrier separation due to ultrafast intramolecular charge transfer. The boosted performance is closely related to the deliberately introduced D-A structure, which may offer insights for designing analogues with better photocatalytic hydrogen evolution performance.
