Hao Tan et al.

Summary: The study shows that publications on green energy and environmental technologies have grown exponentially, with China, the USA, and Italy being the most active countries, but global cooperation is not closely knit at present. The research frontier identification results indicate that categories such as energy, wastewater, and performance are stable, while catalyst and CO2 emission categories show a clear shift, suggesting that catalytic production of clean energy, strategies to reduce greenhouse gas emissions, and related studies are the research frontiers to address global energy crisis and environmental problems.

Unravelling intramolecular charge transfer in donor-acceptor structured g-C3N4 for superior photocatalytic hydrogen evolution

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.
