In article number 1703484 Jimmy C. Yu and co‐workers report how adding red P nanoparticles onto g‐C3N4 effectively suppresses charge trapping and thus prolongs the lifetime of active charges in the photocatalyst. The optimized red P/g‐C3N4 composite exhibits a very high photocatalytic hydrogen evolution rate of 2565 μmol h−1 g−1. The charge trapping/de‐trapping processes are thoroughly investigated...
The high occurrence of trapped unreactive charges due to chemical defects seriously affects the performance of g‐C3N4 in photocatalytic applications. This problem can be overcome by introducing ultrasmall red phosphorus (red P) crystals on g‐C3N4 sheets. The elemental red P atoms reduce the number of defects in the g‐C3N4 structure by forming new chemical bonds for much more effective charge separation...
