Electron trap engineering in g-C 3 N 4 with molecular Mo 3 S 4 clusters for visible-light-driven photocatalysis

[Mo 3 S 4 Cl 3 (en) 3 ]Cl clusters modulate g-C 3 N 4 electronically, creating trap states that enhance charge separation and visible-light activity, unveiling a new route to tailor photocatalysts for efficient ROS generation and pollutant degradation.
